title: NSwag - how do I add comments?
body: <p>I use NSwag in an ASP.Net WebAPI project to generate a swagger interface - which works great.</p>
  <p>Say I have a method I want to add some explanations to - how can I do that?</p>
  <p>By comment I mean something that when a user of the API is looking at the documentation will see.</p>
  <p>I have googled, binged and ... ducked? - but was unable to find anything about it. Maybe I am using wrong terms.</p>
