I have, for now, stopped raising doc PRs because of the long backlog - I have, for instance, some doc PRs which were raised 8 months ago which have not yet been reviewed. Until the backlog shifts, I’m not likely to raise more PRs.
This is not a complaint, I do realise reviewing takes time, and no-one has the time to do it.
For anyone thinking of raising doc PRs, I found this guide extremely useful: A plea for help writing the docs - #22 by hatsnp
And this is a list of darktable PRs with documentation pending (but check there is not an open dtdocs PR before starting on one of these): Pull requests · darktable-org/darktable · GitHub
