-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!).  Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
-
-## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
-
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
-
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
-
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
-
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
-
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
-
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
-
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
-
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
-
-## License
-For open source projects, say how it is licensed.
-
-## Project status
-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.

+
+### Versuchsaufbau
+
+Bauen Sie ein erstes Fahrzeug aus den gegebenen LEGO-Teilen in der CAD-Software LeoCAD auf.
+
+Hierbei gelten die folgenden Rahmenbedingungen:
+- Das Fahrzeug muss aus Baugruppen, Bauteilen und Komponenten bestehen.
+- Es muss mindestens vier Räder besitzen
+- Es muss sich durch den elektrischen Antrieb fortbewegen können.
+- Die Verwendung eines Getriebes zwischen Motor und Antriebsachse(n) ist verpflichtend.
+- Die Farbe von mindestens einem Teil soll sich von der in LeoCAD hinterlegten Standardfarbe unterscheiden.
+- Es sind nur die LEGO-Teile zu verwenden, welche sich in den JSON-Dateien bzw. in
+der zur Verfügung gestellten Teilebibliothek befinden.
+
+%% Cell type:markdown id:0ebba2d8 tags:

+Fügen Sie eine Abbildung des fertigen Autos in LeoCAD hinzu (*Hinweise: Ein Bild lässt sich mit \!\[Bildbeschreibung](/Pfad/zum/Bild) hinzufügen. Achten Sie darauf, das Bild später auch in Git hinzuzufügen*):

+
+%% Cell type:markdown id:df7f1d01 tags:
+
+
+%% Cell type:markdown id:e622f83b tags:
+
+Bauen Sie das Fahrzeug nun in unserem Software-Framework zusammen. Instanziieren Sie die LEGO-Teile und lesen Sie dabei auch die Eigenschaften ein. Ergänzen Sie zusätzliche Eigenschaften, wie z.B. die Farbe. Referenzieren Sie die Teile aufeinander und erstellen Sie auf diese Weise sinnvolle Bauteile, Baugruppen und das
+Gesamtsystem. Nutzen Sie die hierfür bereitgestellten Klassendefinitionen und Methoden. Achten Sie auf eine gute Code-Dokumentation. Sie können sich für die Bearbeitung an den zur Verfügung gestellten Code-Zellen orientieren, können hiervon jedoch auch abweichen.
+
+*Hinweise: Achten Sie auf die Unterschiede zum Minimalbeispiel. Eine direkte Kopie ist nicht möglich. Achten Sie außerdem darauf, ein Teil (eindeutig identifiziert durch seine UUID) nicht an mehreren Stellen zu verbauen*

+### Analyse
+Bestimmen Sie die Qualität Ihres Fahrzeugs mittels KPIs.
+Die Qualität des Fahrzeugs ist mit mindestens einem KPI je Qualitätsdimension (Aufwand, Verfügbarkeit, Akzeptanz) zu bestimmen. Enwickeln Sie zunächst sinnvolle KPIs, welche mit den gegebenen Daten umsetzbar sind. Halten Sie die Berechnungsvorschriften im Jupyter Notebook fest. Implementieren Sie deren Berechnung für das Gesamtsystem "Fahrzeug" mittels einzelner Funktionen im Skript `calculation_rules`. Sie können zusätzlich Ihre Methoden auch auf die niedrigeren Aggregationsebenen anwenden.
+
+%% Cell type:markdown id:d5f02096 tags:
+
+Beschreiben Sie den jeweiligen KPI und geben Sie seine Berechnungsvorschrift an:
+
+%% Cell type:markdown id:a793bce8 tags:

+a = \frac{b}{c} + d
+$$

+
+``` python
+# calculate the KPIs for your car
+```
+
+%% Cell type:code id:c774b381 tags:

+
+%% Cell type:markdown id:b89e8fb9 tags:
+
+Exportieren Sie schließlich Ihr entworfenes Fahrzeug inklusive der entwickelten KPIs:
+

+%% Cell type:markdown id:f8a2e1b0 tags:
+
+### Versuchsziel
+
+%% Cell type:markdown id:80407e7f tags:
+
+Setzen Sie sich ein Ziel, welche Qualitätsdimensionen in einem zweiten Fahrzeug verbessert werden sollen und bauen
+Sie darauf aufbauend ein zweites Fahrzeug aus den gegebenen LEGO-Teilen auf.
+Die Anforderungen an das Fahrzeug sind identisch zum ersten. Wählen Sie die Einzelteile und deren Zusammenspiel entsprechend Ihrer Zielstellung aus.
+
+%% Cell type:markdown id:f4c620ee tags:
