title: Writing an Excel Addin User Guide
body: <p>I've created an addin for Excel containing a number of different functions. Now, I need to create a user guide (a set of webpages will suffice) defining what the functions do; their inputs and their outputs. </p>
  
  <p>Are there any tools that will help me do this? Has anyone seen any good examples recently, or shall I just mimic Excel Help?</p>
