A huge selling point for a CMS is the documentation available. Backdrop has some pretty good documentation, but I have the feeling that we have not been keeping it current or fleshing it out very well. Creation of documentation seems to have stagnated somewhat. Also, for someone as involved in the community, even I am a bit confused about the process for improving, editing, or adding to the documentation.
I think that we could benefit from an initiative focused on making it easier to add to and update documentation and making sure that we have good documentation for end users / site owners.
