You can expect it to grow into a mature documentation source, and probably rather quickly, knowing the community on Slack.
Huge thanks to @aderks, @thebaron, @stuf, @philipmarshall, and @86b for making a start in #dx-doc-team (in Slack). Anyone is welcome to join in editing or commenting on documents. You can make any change you want and submit a pull request. Go for it. Get involved. If you need help, ask in #dx-doc-team.
Here's to a future where anyone can find their questions well-answered easily.
