Where is the SteamVR/ Vive API documentation?

Is there a full SteamVR API documentation? Say I want to know more about the SteamVR_Controller.Input method, as a for instance.


SteamVR API documentation… contains trouble shooting for SteamVR and Vive Pre


The closest thing I know of is the
actual OpenVR API Documentation. The
Unity package is just a C# wrapper for
the C++ dlls. Most of the C++ calls
are available through the C# wrappers,
though some of the latest ones might
not be available in the Unity package

documentation is here but it is not very useful for me atm

There is new SteamVR Unity Plugin documentation up on the github here: SteamVR Unity Plugin | SteamVR Unity Plugin
