Problem: we can use the existing tutorial to make a static website
for Indigo using mkdocs.
This needs changed in the documentation's content, namely:
- we would like to statically include part of the example modules
- there needs to be an index/home page
- the appendices should be moved to be "reference" pages
- the explanations should not be flat, but include note blocks, etc.
- references to local files need to be removed, as they don't work

Solution: Make a buildable website with:
- configuration for mkdocs and its extension
- CSS for customized styling
- a python-markdown extension for example source code inclusion
