Documentation

Quick Start documentation for Gaia lives in the Procedural Worlds / Gaia / Documentation directory.

Additionally, all Panels in the Gaia user interface will show a ? which you can click on in order to toggle inline help.

This is actually the best way to understand what the various settings do, and is always the most up to date version of the Gaia Documentation, and Tutorials.
