Thanks to Patrick we have a Helix wiki space. https://cwiki.apache.org/confluence/display/HELIX/Index
I will try to port the documents we have on Helix at LinkedIn into this space. We should also try using this to write up design notes and ideas. If you need permission to add pages let me know your account ids.(Note this is not apache id, you can sign up here https://cwiki.apache.org/confluence/signup.action) thanks, Kishore G
