<p>I want to format my existing comments as 'RDoc comments' so they can be viewed using <code>ri</code>.</p>

<p>What are some recommended resources for starting out using RDoc?</p>

RDoc uses SimpleMarkup so it's fairly simple to create lists, etc. using *, - or a number. It also treats lines that are indented at the same column number as part of the same paragraph until there is an empty line which signifies a new paragraph. Do you have a few examples of comments you want RDoc'ed so we could show you how to do them and then you could extrapolate that for the rest of your comments?
