2. Run the Rake task:

3. Add helper to any controllers you want to use markdown_preview with:

     class MyController < ApplicationController

4. Add the helper tag to your base layout:

   <!-- Note, jQuery include *required* above this line. -->
   <%= include_markdown_preview_if_needed %>

5. (Optional) If you want to override the preprocessor then add the following to config/initializers/markdown_preview.rb

   module MarkdownPreview
    
     #Write your own preprocessor here if you want to
     #the md param is the incoming markdown text, before it has been processed
     def self.preprocess_markdown( md )
       md 
     end
   
   end

6. Add the markdown_preview class to any textareas you want to be previewable, and you're good to go!
