Quick Notes

• Haml Coffee is usually indented with two spaces, although more than two is allowed. You have to be consistent, though.
• The first character of any line is called the "control character" - it says "make a tag" or "run CoffeeScript code" or all sorts of things.
• Haml takes care of nicely indenting your HTML.
• Haml Coffee allows CoffeeScript code and blocks.

You can get more information by reading the Official Haml Coffee Documentation

CoffeeScript code is included by using = at the beginning of a line.
