For many years we’ve been using MediaWiki for Synfig documentation.
And there were a lot of problems with that:
MediaWiki is hard to maintain (update version), it is affected by spambots and it is missing many features (like export of documentation to various formats).
Today we have a lot of other solutions and Sphinx docs (+ReadTheDocs) is looks like a common standard. (Our developer’s documentation is already in ReadTheDocs and sources are stored on GitHub).
Also, the documentation on MediaWiki is very much outdated.
So, I suggest to start with re-writing documentation of Synfig in ReadTheDocs format.
Here is a repository - https://github.com/synfig/synfig-docs
And here is a “rendered” documentation - https://synfig.readthedocs.io/en/latest/index.html
At the moment all pages are empty - I just created a basic structure, hope this will be a good starting point.
Please note, that we cannot blindly “copy-paste” docs from MediaWiki to GitHub repo because Mediawiki docs are licensed under CC-BY-SA. The latter makes it problematic to re-use, because requirement of this license is to track and list all previous contributors. This could be problematic in some situation, for example if we will want to publish a book based on manual. Considering that most of documentation is outdated anyway, I think that re-writing it completely under Public Domain license will be easier.
To assist with this process I suggest to apply for Google Season of Docs this year. ^___^
