 ## Syntax
 
-We don't have a syntax reference for `HAML.jl` yet. It mostly follows
-[Ruby's syntax document](http://haml.info/docs/yardoc/file.REFERENCE.html) with
-the following exceptions:
-
- - use named tuple syntax for attributes
- - use `- @include` for including `.hamljl` files.
-
- See the [test cases](test/runtests.jl) for examples.
+If you are already familiar with Ruby-flavoured HAML, [read about the
+differences here][fromruby]. If not, either use read the [getting started guide][gettingstarted]
+or the [syntax reference][syntax].
