#haml.docs
Tutorial
The tutorial is a great place to start if you aren’t familiar with the language. It goes over the basic syntax for elements, as well as how to embed Ruby in the document.
Haml Reference
The Haml reference is the most complete documentation for Haml. It contains information on every language feature, all the options, and how to install it as a Rails plugin.
Community
Haml 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 Haml IRC channel, #haml 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 you have a longer question (or no one’s around on IRC at the moment), the Haml 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 Haml community.
API Documentation
Finally, if you want to look at the Haml 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 Haml, that’s a good place to look.
