You can contribute to Camping in several ways. For starters:
- check through the issues and see what you can do
- join the mailing list and help out answering questions
- be available on IRC (#camping @ irc.freenode.net) when you can
- write something useful on deployment for your setup (for example)
- try something new and let the community know how it went
- send your Camping app/site to the mailing list so it can be included
- help us finish the website
You don't have to be a Ruby expert, but that helps too...
