Add the gem to your assets group in the Gemfile:

gem 'therubyracer'
gem 'less-rails'
gem 'less-rails-fontawesome'

Get the full Fontawesome stylesheet with a single line in your application.css:

 *= require font-awesome/font-awesome

Alternatively, remove app/assets/stylesheets/application.css and create app/assets/stylesheets/application.less with the content

@import 'font-awesome/font-awesome';

You can also use it with the less-rails-bootstrap gem. Just import fontawesome right after twitter/bootstrap:

@import 'twitter/bootstrap';
@import 'font-awesome/font-awesome';

To place Font Awesome icon add i element and set its class attribute to a icon name, for example:

<i class="fa fa-camera-retro"></i>

To ease placing icons in Rails link_to helper use the fa_link_to helper method.

For example, to place the fa-upload icon next to Edit write something like:

<%= fa_link_to "upload", "Edit", edit_post_path(post), class: 'btn btn-mini' %>

or to place trash-o next to text Destroy button write:

<%= fa_link_to "trash-o", "Destroy", post, data: { confirm: "Are you sure?" },
       method: :delete, class: 'btn btn-mini btn-danger'%>

(precede the link text with the icon name stripped off fa- prefix)
