For better documentation, I think it’d also be a good idea to migrate some of the notes in forums to corresponding fastai docs, often it’s very difficult to find some of those gems in the forums.
So if you stumble upon useful summaries, tips, performance notes, and other useful information that can be extracted/compiled into a stand-alone document or a section of an existing one, that would be a great service to this community.
In general we put normal user docs under fastai’s repo docs/*md, and more of the core dev docs under docs/dev/*md, but don’t worry too much about the proposed placement - it’s easy to reorganize those later.
Reading through some of the posts by @jeremy and @sgugger is probably a good starting point, but there are plenty other wonderful contributions by others hidden in the forums.
