Also, the documentation for erubis (a better, faster implementation of 
erb) is pretty good. Since they implement the same base feature set, 
this should help you.

To be honest, there's nothing much you need to know about erb in Rails.

<% if foo %>
...
<% end %>

<%= some_expression %>

<%=h some_expression_which_needs_html_escaping %>
