Tutorial

The tutorial is a great place to start if you aren’t familiar with the language. It covers getting set up with Sass and the basic features of the language.

Sass Reference

The Sass reference is the most complete documentation for Sass. It contains information on every language feature, all the options, and how to install it as a Rails plugin.

Books

There are two books out about Sass (and Compass).

Community

Sass has a thriving community that’s eager to help out. There are several places where you can go to ask questions or help you debug problems. The Sass IRC channel, #sass on irc.freenode.net, is a great place to ask short questions that you want answered quickly. Feel free to ping nex3 if he’s there to get his attention quickly. If there’s no one on #sass, the #compass channel is worth trying as well.

If you have a longer question (or no one’s around on IRC at the moment), the Sass Google group is a great place to go. You’ll usually get a response within a couple hours or so.

FAQ

If you’re having trouble or have a question, try the FAQ. If you don’t find what you’re looking for there, ask the Sass community.

API Documentation

Finally, if you want to look at the Sass implementation, check out the YARD API documentation. This probably won’t be too useful for most people, but if you’re writing Ruby code to interact with Sass, that’s a good place to look.
