The configuration for mkdocs lies in the `docs` folder in a file called `mkdocs.yml`. With that file the theme and menu - among others - can be configured.
**Please note:** Any new files need to be linked to by other files or put in the navigation, otherwise the files will be very hard to find on the documentation website.
The repository [docs.hedgedoc.org](https://github.com/hedgedoc/docs.hedgedoc.org) is used to deploy the actual website to github.io. Currently only the `master` branch is deployed as it contains the latest release.
