+# Documentation
+
+Our documentation is build with [mkdocs](https://www.mkdocs.org).
+
+## Writing
+
+All documentation files are found in the `docs` directory of the [hedgedoc/hedgedoc repo](https://github.com/hedgedoc/hedgedoc). These files are just normal markdown files with nothing special about them.
+
+The config file for mkdocs lies in the root of the repo in a file called `mkdocs.yml`. With that file the theme and menu - amoung others - can be configured.
+**Please note:** Any new files need to be linked to by other files or put in the navigation or the files will be very hard to find on the documentation website.
+
+## Building
+
+To build the documentation locally you need to perform the following steps:
+
+1. make sure you have python3 installed
+2. install all the dependencies possibly with a [venv](https://docs.python.org/3/library/venv.html):  
+`pip install -r mkdocs.requirements.txt`
+3. start the mkdocs dev server `mkdocs serve` or let it build the documentation `mkdocs build`
+
+## Deployment
+
+The documentation is deployed with [Messor Structor](https://github.com/traefik/structor).
+
+The necessary Dockerfile and version menu template and also the github action to build the whole documentation can be found in the [docs.hedgedoc.org repo](https://github.com/hedgedoc/docs.hedgedoc.org). This repo is also used to deploy the actuall website to github.io.
+
+Messor Structor builds and deploys the documentation by finding all branches that follow the pattern `v*` and build each one seperatly via `mkdocs` by first installing `mkdocs.requirements.txt` and then building. Afterwards the menu go template is used to include a version switcher in the theme and make all the different versions available.
