#3 is one of my favorite things about Sidekiq. Anything I'm trying to do with Sidekiq, I check the wiki first, and it's usually there. Any time I've introduced the library to a team, the docs and wiki are always my recommendation for answering questions. Even Pro/Ent features are covered there, which is so much nicer than having the docs hidden behind a login/paywall.

Thanks for the hard work you've poured into them Mike!
