Over the years, a lot of changes have slipped into the game without the appropriate help files being updated. On top of that, there is always room for improvement of documentation.
This thread exists to have a unified place to make suggestions for help file improvements. This includes fixing/updating/expanding existing files, as well as making new ones.
The most helpful thing you can do is include the specific information that should be updated (including what to update it to), but mentioning which help files need love is also good.
As always, you can also file typo reports in-game, but this gives a bit more of a long-form venue and area for discussion.
