Community translations
We could provide community translated documentation. This doesn't mean that we should tell users that it is authoritative but we could allow users to translate it somehow.
The idea is to use same framework as rest of our tools that means weblate. That means we have to generate pot files from our markdown and later on translate it.
Example of script and project doing that is https://github.com/tvheadend/tvheadend-documentation/blob/master/tvhmd.py
