title: Simple Rails 3 blog
body: <p>I have an app that I would like to add a blog to. I'd like to integrate it with my current site.  I only have a few simple requirements:</p>
  
  <ul>
  <li>Being able to add formatting (headers, paragraphs, etc..)</li>
  <li>Adding images that can be embedded in the content.</li>
  <li>Categories</li>
  </ul>
  
  <p>That's it! I don't want to start from scratch, so a simple gem would be ideal. I don't want a big full featured blog because it will undoubtebly contain many things I don't need. Is there a gem that will allow me to add this functionality to my site easily, or should I just go ahead and build it myself? If so, do you have any resources that could help me with my first 2 requirements (I don't know how exactly I could make paperclip work with the second one)</p>
  
  <p>I'll be hosting this site on Heroku.</p>
  
  <p>Thanks!</p>
