 ## Files that require changes by the module manager
 The code is designed to be highly generalized, meaning that only a few files need changes by the module manager. These files are shown in the following image and are discussed below in more detail. In some parts of the code, dynamic import commands and function names are generated, with examples provided at relevant points to illustrate how these commands work.

-   - **Unix/macOS:** `python3 -m pip install --upgrade pip`
-   - **Windows:** `python -m pip install --upgrade pip`
+    - **Unix/macOS:** `python3 -m pip install --upgrade pip`

+![](../../assets/images/developer/style/modularization/python-modularization_11_unicado-python-library.png)
 
 ## Step 1: Create the package subfolder
 In `unicado_python_library`, create a new subfolder for the package. Follow this naming convention:
+
 - **Format:** `py[name of package]package` (all lowercase, without underscores)
 - **Example:** `pymodulepackage`
-
+  
 Then, navigate into this subfolder.
 
 ## Step 2: Create a `pyproject.toml` file
 The `pyproject.toml` file contains information on the build backend (`[build-system]`). We are using setuptools. Furthermore, this file contains core metadata for packaging-related tools to consume (`[project]`, `[project.urls]`).

 ## Step 5: Create `src` subfolder
 Inside the package folder, create a `src` subfolder to hold the `.py` files (modules).
-- **Convention:** Each `.py` file should correspond to a single module, named in this format:
-  - **Format:** `[module name]module.py` (all lowercase, no underscores)

+  
 Modules can contain several functions. Once files are set up, return to the main package folder before proceeding.
 
 ## Step 6: Execute installation command
 In the directory containing `pyproject.toml`, run the following installation command:
+
    - **Windows:** `python -m pip install -e .`
    - **macOS:** `python3 -m pip install -e .`
 
 **Explanation:**

+# Getting started
+This guide will show you the basic usage of _cost_estimation_. The following steps are necessary (if you are new to UNICADO check out the [settings and outputs](#settingsandoutputs) first!).
+
+## Step-by-step
+It is assumed that you have the `UNICADO package` installed including the executables. In case you are a developer, you need to build the tool first (see [build instructions on UNICADO website](https://unicado.pages.rwth-aachen.de/unicado.gitlab.io/developer/build/general/))
+
+
+Execute the following steps to run the module:
+1. Create a dummy `aircraft_exchange_file` (minimal required input see [here](#acXML))
+2. Fill out the `cost_estimation_conf.xml` - change at least:
+    - in the `control_settings` block
+        - `aircraft_exchange_file_name` and `aircraft_exchange_file_directory` to your respective settings
+        - `console_output` at least to `mode_1`
+        - `plot_output` to false (or define `inkscape_path` and `gnuplot_path`)
+    - in `program_settings`
+        - ...
+3. Open terminal and run `cost_estimation`
+
+The following will happen:
+- You see output in the console window
+- A HTML report is created in the directory of the aircraft exchange file (no plots are generated if they are turned off)
+- Results are saved in the aircraft exchange file at the `aircraft_exchange_file/assessment/cost_estimation/operating_cost` node
+
+@note The dummy does not include any aircraft data. Therefore the cost estimation will not work and warnings are expected in the output.
+
+## Settings and outputs {#settingsandoutputs}
+Generally, we use two files to set or configure in UNICADO:
+- the aircraft exchange file (or _acXML_) includes
+    - data related inputs (e.g., aircraft configuration, transport task)
+    - data related outputs (e.g., annual direct operating costs)
+- the configuration file `cost_estimation_conf.xml` (also _configXML_) includes
+    - control settings (e.g., enable/disable generating plots)
+    - program settings (e.g., fees, usage information)
+
+### Aircraft exchange file
+@note The _acXML_ is an exchange file - we agreed on that only data will be saved as output that is needed by another tool!
+
+#### Inputs
+The following information is needed from the _acXML_:
+1. Design specification
+    1. Configuration information: Configuration type
+    2. Transport task: Passenger definition, passenger class definition, and cargo definition
+    3. Energy carriers
+2. Top level aircraft requirements (for design and study mission - if desired)
+    1. Initial cruise mach number
+    2. Initial cruise altitude
+    3. Payload fractions (seat load factor, only required for study mission assessment)
+3. Component design
+    1. Fuselage: Number of required cabin crew
+    2. Propulsion: Sea level static thrust per engine
+4. Analysis
+    1. Masses: Maximum takeoff mass (certified), operating mass empty, maximum payload mass
+    2. Mission (for design and study mission - if desired)
+        - Range
+        - Flight time
+        - Payload mass
+        - Number of passengers
+        - Number of flight crew
+        - Cargo mass
+        - Takeoff mass
+5. Assessment (aka. payload range data)
+    1. Range at maximum payload and fuel mass till maximum take off mass limit
+    2. Range at full tanks and payload till maximum take off mass limit
+    3. Range for no payload and full tanks (ferry range)
+    4. Payload at full tanks and payload till maximum take off mass limit
+
+#### Outputs
+The essential results are saved in the _acXML_ node `aircraft_exchange_file/assessment/cost_estimation/operating_cost/direct_operating_cost`.
+When implemented, the indirect operating costs are going to be saved at `aircraft_exchange_file/assessment/cost_estimation/operating_cost/indirect_operating_cost`.
+
+```plaintext
+Direct operating cost
+|- Route independent cost annual
+|- Route dependent cost annual
+|- Direct operating cost annual
+```
+
+Further information can be extracted from the additional output file.
+
+### Configuration file
+The control settings are standardized in UNICADO and will not be described in detail here. The program settings are structured like this (descriptions are in the `cost_estimation_conf.xml`):
+
+```plaintext
+Program Settings
+|- Configuration (ID="tube_and_wing")
+|  |- Fidelity name
+|  |- Method name
+|  |- Fidelity (ID="empirical")
+|  |  |- Operating cost estimation tu berlin
+|  |  |  |- General direct operating costs parameter
+|  |  |  |  | - Capital
+|  |  |  |  |  | - Depreciation period
+|  |  |  |  |  | - Price per operating empty mass

+|  |  |  |  |  | - Rate labor
+|  |  |  |  | - Related direct operating costs
+|  |  |  |  |  | - Revenue per freight km design
+|  |  |  |  |  | - Revenue per freight km study
+|  |  |  |  | - Miscellaneous
+|  |  |  |  |  | - Rate inflation
+|  |  |  |- Fuel type (ID="kerosene")
+|  |  |  |  | - Factor engine maintenance
+|  |  |  |  | - Fuel price
+|  |  |  |  | - Ratio operating empty mass
+|  |  |  |- Fuel type (ID="liquid_hydrogen")
+|  |  |  |  | - Factor engine maintenance
+|  |  |  |  | - Fuel price
+|  |  |  |  | - Ratio operating empty mass
+```
+
+## Minimal required aircraft exchange file input {#acXML}
+As the _cost_estimation_ tool is part of the assessment modules in UNICADO, it is based on the assumption that a converged design and a correspondingly complete _acXML_ file are already available. The following parameters are required to generate results with the tool.

+# Introduction {#mainpage}
+Welcome to the _cost_estimation_ module in UNICADO. [...]
+
+## Summary of features
+Here’s a quick rundown of what the tool currently does, along with a sneak peek at what's planned:
+
+ Configuration    | Fidelity  | Method(s) | Energy carrier  |Cost share               | Status                         |

+
+## Ready for takeoff
+The [getting started page](getting_started.md) provides an initial understanding of how to execute the tool and its fundamental operations. For a comprehensive understanding of the tool’s functionality, the documentation is structured into two distinct sections: a [method description](operating_cost_method.md) and a [software architecture](software_architecture.md) section.

+    This function is responsible for preparing the user-specific output data based on the results of the calculation

+    The data for the key parameters output must be specified in the following format in order to be written correctly

+        case, errors may occur subsequently resulting in the write process and consequently the entire program being
+        aborted.
+        (3) If the path specifications contain IDs, these must start at '0' and be defined in ascending order without
+        gaps.
+    For the method-specific output, a path list and a dictionary is necessary to properly write the data to the
+    method-specific XML file.

+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    UNICADO - Modular Preliminary Aircraft Design Tool
+    Copyright (C) 2024
+
+    This program is free software: you can redistribute it and/or modify

+        (1) Preparation: Using the paths contained in the 'user_output_dict', a list with user paths is generated that
+        is subsequently cleaned of duplicates. Next, every path in the path list is assigned to one of the four
+        categories and appended to the corresponding list:

+        Note: Only the paths of the last category will be considered further in the following steps.
+        For further processing, the paths in 'user_paths_to_check_list' are sorted in ascending order according to
+        their IDs. In addition, all paths that have one or more IDs are then extracted from the key paths and appended
+        to 'key_paths_with_id_list' for further use.
+        (2) Path validation and key parameter check: One by one, each key path is generalized. This means that the
+        number(s) of the ID(s) contained are replaced by an 'X'. All user paths from 'user_paths_to_check_list' are
+        checked to see whether they match the pattern of the current generalized key path. All paths that match this
+        pattern are added to the 'matching_user_paths_list'. If there are matching user paths, the code performs
+        various checks to assign these user paths to either the 'valid_user_paths_list' or 'invalid_user_paths_list'.
+        The checks include examining the structure and values of IDs within the user paths. After processing the key
+        paths, the code checks for any user paths that are neither in the 'valid_user_paths_list' nor in the
+        'invalid_user_paths_list'. These paths are considered invalid, and a warning is issued. If there are user path
+        errors, error messages are generated, and the program is prepared for possible abort. The code checks whether
+        all key parameters are written by the user. If any key parameter path is missing, an error message is issued.
+        If there are either user path errors or missing key path errors, the code generates error messages and,
+        depending on the error type, raises a ValueError exception. This exception serves as a signal to terminate the
+        program.
+        Note: Only the 'valid_user_path_list' will be considered further in the following steps.
+        (3) Initialization of tree structure: Ensure that all necessary paths exist in aircraft exchange file to enable
+        upcoming step. Furthermore, the values are checked to ensure that they are within the defined limits.

+    """General data preprocessing for current calculation method.
+
+    This function performs general data preprocessing on input data obtained from aircraft exchange and module
+    configuration files. It accomplishes the following tasks:
+        (1) Data preparation: Extract root elements of aircraft exchange and module configuration trees from
+        'paths_and_names' dict. Invoke 'user_method_data_preparation' function, specified in 'routing_dict', to obtain
+        information on data to extract from these files, resulting in two dictionaries, namely the
+        'data_to_extract_from_aircraft_exchange_dict' and the 'data_to_extract_from_module_configuration_dict'.
+        (2) Read values from XML files: Using the above defined dictionaries with information on parameters that must
+        be extracted from the aircraft exchange and module configuration file, the according values are read from the
+        respective files and stored in 'tmp_aircraft_exchange_dict' and 'tmp_module_configuration_dict'. These
+        temporary dictionaries have a specific format for each parameter, including the parameter's name, path, value,
+        lower boundary, and upper boundary:
+            tmp_dict = {'parameter_name_1': [path, expected data type, value, lower boundary, upper boundary],
+                        'parameter_name_2': [...],
+                        ...}
+        (3) The code then iterates over both temporary dictionaries, type casts the values to their expected data types,
+        checks if the values are within specified lower and upper boundaries, and stores the checked values in a new
+        dictionary, 'dict_out_short'. This dictionary contains the values for the same parameters as the input
+        dictionaries but with checked and possibly modified values.
+    The code returns two dictionaries: 'short_aircraft_exchange_dict' and 'short_module_configuration_dict', that
+    represent the preprocessed data for the aircraft exchange and module configuration file, respectively. The
+    dictionaries represent condensed forms of the 'tmp_aircraft_exchange_dict' and the 'tmp_module_configuration_dict'
+    and are structured according to the following scheme:
+        dict = {'parameter_name_1': value, ...}
+
+    In the case of a multi-parameter (xml path contains '@ID' identifier), the value of the parameter key
+    ('parameter_name_1') contains a sub-dictionary with all existing parameter ID names ('parameter_name_1_ID...') and
+    its corresponding values.
+        dict = {'parameter_name_1': {'parameter_name_1_ID0': value, 'parameter_name_1_ID1': value}, ...}

-# Getting started
-This guide will show you the basic usage of _cost_estimation_. The following steps are necessary (if you are new to UNICADO check out the [settings and outputs](#settingsandoutputs) first!).
-
-## Step-by-step
-It is assumed that you have the `UNICADO package` installed including the executables. In case you are a developer, you need to build the tool first (see [build instructions on UNICADO website](https://unicado.pages.rwth-aachen.de/unicado.gitlab.io/developer/build/general/))
-
-
-Execute the following steps to run the module:
-1. Create a dummy `aircraft_exchange_file` (minimal required input see [here](#acXML))
-2. Fill out the `cost_estimation_conf.xml` - change at least:
-    - in the `control_settings` block
-        - `aircraft_exchange_file_name` and `aircraft_exchange_file_directory` to your respective settings
-        - `console_output` at least to `mode_1`
-        - `plot_output` to false (or define `inkscape_path` and `gnuplot_path`)
-    - in `program_settings`
-        - ...
-3. Open terminal and run `cost_estimation`
-
-The following will happen:
-- You see output in the console window
-- A HTML report is created in the directory of the aircraft exchange file (no plots are generated if they are turned off)
-- Results are saved in the aircraft exchange file at the `aircraft_exchange_file/assessment/cost_estimation/operating_cost` node
-
-@note The dummy does not include any aircraft data. Therefore the cost estimation will not work and warnings are expected in the output.
-
-## Settings and outputs {#settingsandoutputs}
-Generally, we use two files to set or configure in UNICADO:
-- the aircraft exchange file (or _acXML_) includes
-    - data related inputs (e.g., aircraft configuration, transport task)
-    - data related outputs (e.g., annual direct operating costs)
-- the configuration file `cost_estimation_conf.xml` (also _configXML_) includes
-    - control settings (e.g., enable/disable generating plots)
-    - program settings (e.g., fees, usage information)
-
-### Aircraft exchange file
-@note The _acXML_ is an exchange file - we agreed on that only data will be saved as output that is needed by another tool!
-
-#### Inputs
-The following information is needed from the _acXML_:
-1. Design specification
-    1. Configuration information: Configuration type
-    2. Transport task: Passenger definition, passenger class definition, and cargo definition
-    3. Energy carriers
-2. Top level aircraft requirements (for design and study mission - if desired)
-    1. Initial cruise mach number
-    2. Initial cruise altitude
-    3. Payload fractions (seat load factor, only required for study mission assessment)
-3. Component design
-    1. Fuselage: Number of required cabin crew
-    2. Propulsion: Sea level static thrust per engine
-4. Analysis
-    1. Masses: Maximum takeoff mass (certified), operating mass empty, maximum payload mass
-    2. Mission (for design and study mission - if desired)
-        - Range
-        - Flight time
-        - Payload mass
-        - Number of passengers
-        - Number of flight crew
-        - Cargo mass
-        - Takeoff mass
-5. Assessment (aka. payload range data)
-    1. Range at maximum payload and fuel mass till maximum take off mass limit
-    2. Range at full tanks and payload till maximum take off mass limit
-    3. Range for no payload and full tanks (ferry range)
-    4. Payload at full tanks and payload till maximum take off mass limit
-
-#### Outputs
-The essential results are saved in the _acXML_ node `aircraft_exchange_file/assessment/cost_estimation/operating_cost/direct_operating_cost`.
-When implemented, the indirect operating costs are going to be saved at `aircraft_exchange_file/assessment/cost_estimation/operating_cost/indirect_operating_cost`.
-
-```plaintext
-Direct operating cost
-|- Route independent cost annual
-|- Route dependent cost annual
-|- Direct operating cost annual
-```
-
-Further information can be extracted from the additional output file.
-
-### Configuration file
-The control settings are standardized in UNICADO and will not be described in detail here. The program settings are structured like this (descriptions are in the `cost_estimation_conf.xml`):
-
-```plaintext

-```
-
-## Minimal required aircraft exchange file input {#acXML}
-As the _cost_estimation_ tool is part of the assessment modules in UNICADO, it is based on the assumption that a converged design and a correspondingly complete _acXML_ file are already available. The following parameters are required to generate results with the tool.
-
-```xml

-# Introduction {#mainpage}
-Welcome to the _cost_estimation_ module in UNICADO. [...]
-
-## Summary of features
-Here’s a quick rundown of what the tool currently does, along with a sneak peek at what's planned:
-
- Configuration    | Fidelity  | Method(s) | Energy carrier  |Cost share               | Status                         |

-## Ready for takeoff
-The [getting started page](getting_started.md) provides an initial understanding of how to execute the tool and its fundamental operations. For a comprehensive understanding of the tool’s functionality, the documentation is structured into two distinct sections: a [method description](operating_cost_method.md) and a [software architecture](software_architecture.md) section.
