Documentation
Complete guides, a reference of every setting and error code, and API documentation. The documentation is complete in English and French; the other languages are machine translations that native speakers have not reviewed, and some pages are still in English or carry a notice that they are out of date.
The public version is a development version, 0.3.0-dev. No stable version exists yet.

The documentation also says what is not done or not verified: read the known limits before a production rollout.
