As a TGE user, you have a ton of great documentation and tutorials available to you! This page offers a quick overview of what's available.
There are two main places to get detailed TGE documentation: online at the Torque Developer Network (TDN) and here in the TGE SDK installation on your hard drive itself. The Torque Developer Network is a vibrant, community-oriented online documentation site for TGE and other GarageGames technologies. More information on the documentation available in each place is available in the table below.
All told, TGE ships with over 300 pages of documentation right in the SDK! And sinceit's all in html format, you can now cross-reference all the functions and glossary terms with just a click! Of course, you should know that you don't need to read all of this information to get started with TGB. In fact, just the opposite is true! Most people just read a few tutorials and start working on their own from there. That's all you really need to do... and if you end up having questions later, you can search for answers in the excellent documentation here in the SDK, and online.
Please note as well that all the documents available here in the TGE SDK are also avialable online at the Torque Developer Network.
