+
+[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/git/https%3A%2F%2Fgit.rwth-aachen.de%2FIENT%2Fsignaluebertragung-demos/master?urlpath=lab/tree/index.ipynb)
+
+## Introduction
+
+This repository contains demos for selected topics of the book "Signalübertragung", by Jens-Rainer Ohm (chair of [Institut für Nachrichtentechnik](http://www.ient.rwth-aachen.de)) at [RWTH Aachen University](http://www.rwth-aachen.de) and Hans Dieter Lüke (former chair).
+
+Visit the notebook [index.ipynb](index.ipynb) for a table of contents.
+
+## Quick Start
+
+Run the notebooks directly online [![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/git/https%3A%2F%2Fgit.rwth-aachen.de%2FIENT%2Fsignaluebertragung-demos/master?urlpath=lab/tree/index.ipynb). Please note the following limitations:
+
+* The starting process of the session may take up to one minute.
+* Please note that the session will be cancelled after 10 minutes of user inactivity.
+
+## Usage
+
+To be able to open the demos locally, you need to have a Python environment as well as JupyterLab installed. We recommend to use Anaconda for a local installation.
+
+### Anaconda
+
+To run the notebooks on your local machine, you may use [Anaconda](https://www.anaconda.com/) (using `pip` is also possible for experienced users. You have to install all the requirements listed in `binder/environment.yml` and install the two `jupyter labextension ...` commands listed in `binder/postBuild`).
+
+#### Installation
+
+* Install [Anaconda](https://www.anaconda.com/).
+* Download this repository to your local disk. You can download via `git clone --recurse-submodules git@git.rwth-aachen.de:IENT/signaluebertragung-demos.git`.
+* It is highly recommended to run the notebooks in an isolated Anaconda environment. You can create a new environment called `suelab` from the provided `binder/environment.yml` by running `conda env create -f binder/environment.yml` in the Anaconda prompt. This makes sure that all required packages are installed amd don't interfere with the packages in your base environment.
+* Activate this environment with `conda activate suelab`.
+* Run two final commands in the Anaconda prompt (with activated `suelab` environment):
+
+  ```bash
+  chmod +x binder/postBuild
+  binder/postBuild
+  ```
+
+  If the latter command fails, please open `binder/postBuild` and execute the commands listed there manually.
+
+#### Run
+
+* Activate the environment  with `conda activate suelab`.
+* Run JupyterLab  `jupyter lab`. In your browser, JupyterLab should start. You can then open `index.ipynb` for an overview over all notebooks.
+* You can deactivate the environment with `conda deactivate` (and switch back to it with `conda activate suelab`).
+
+
+## Contact
+
+* If you found a bug, please use the [issue tracker](https://git.rwth-aachen.de/IENT/signaluebertragung-demos/issues).
+* In all other cases, please contact [Christian Rohlfing](http://www.ient.rwth-aachen.de/cms/c_rohlfing/).
