Can we start with a wiki page?

Why a wiki page, instead of documentation?

[hmaarrfk]

Because ASV is so new to the team that we are still learning many small tricks to improve development. I would like to contribute some tips, but definitely cannot write a draft of the whole thing.

For now, the wiki would be like a collaborative document. But maybe I can just add them to this thread?

Why a wiki page, instead of documentation?

I think that Wiki is the preferable solution for:

• WIP features (ASV falls here, for the moment);
• maintenance-related topics (e.g. description of our infrastructure);
• specific (not covered by the upstream docs) questions of using side libraries in scikit-image infra.
