Setup for Sinatra

Setting up RABL on Sinatra is easy. In fact it's as easy as 1..2..3

###Step 1. Install the gem

$ gem install sinatra

###Step 2.

Set up your sinatra app to support RABL:

# app.rb
require 'rubygems' 
require 'sinatra'
require 'rabl'
require 'active_support/core_ext'
require 'active_support/inflector'
require 'builder'

# Register RABL
Rabl.register!

# Render RABL
get "/" do
  @foo = # ...
  render :rabl, :foo, :format => "json"
end

###Step 3.

Now just add a template of type .rabl to match the template referenced in your route to be rendered. For instance, in this case the name of the template is views/foo.rabl

# views/foo.json.rabl

object @foo

# Declarations here

And your done! Now that's what I call easy.
