title: Simple Rails text field formatting
body: <p>How can I easily allow blog posts (in a Rails app) to be formatted? Minimally I'd like to retain the carriage returns when <code>text</code> is displayed as HTML. I guess ideally it'd allow for bold, italic &amp; indentation.</p>
  
  <p>I'm aware of <a href="https://github.com/galetahub/ckeditor" rel="nofollow">CKEditor</a>. I just fear it may be overkill, and difficult to implement quickly &amp; easily...</p>
