+# Build Documentation
+
+## Python Dependencies
+
+In order to generate the documentation,
+first create a Python virtual environment using the
+`venv` module included in Python like this.
+
+* Create a virtual Python environment in the directory `venv` like this.
+
+```
+python3 -m venv venv
+```
+
+* Activate the virtual Python environment like this.
+
+```
+source venv/bin/activate
+```
+
+* Install the packages listed in [requirements.txt](./requirements.txt) using `pip` like this.
+
+```
+pip install -r requirements.txt
+```
+
+## Running Generator via Make
+
+The top level directory contains a Makefile, for generation with all output formats use
+
+`````
+make html
+`````
+
+The output files of the final handbook can be found in the subfolder `./build`.
+
+All generated intermediate artifacts and the final output files can be found in the `./build` subfolder.
+
+### Clean up
+
+1. Deactivate the virtual Python environment: ```deactivate```
+2. Clean up the build sources: ```make clean``` and ```rm -r build bundle```
+
+# File System
