We have separated out the documentation from our main site into a dedicated documentation portal. Separating it into its own site has several advantages, but one is that we can now better facilitate user contributions as many users have offered to assist with documentation.
Check it out and let us know how to improve it. And yes, we know it needs more content. We are working on this and this is part of that effort.
We have also made provisions for multi-lingual content should users wish to contribute content in languages other than English.
