Developers are the last ones to write their own documentation and the first to complain when another hasn't done it. Fortunately for you, we have a smattering of some docs available for your reading pleasure.

User's Guide

The user's guide reads like a book. It has descriptive narratives and examples of using the individual parts of the Xyster Framework.

API

The API is automatically generated by phpDocumentor. It's a low-level specification detailing every last class and method. Very boring, we know, but extremely useful if you don't want to hunt around in the actual source code. You can also take a look at the incubator API.
