title: Doxygen groups and modules index
body: <p>I am creating a Doxygen document for my project. Recently, I have grouped related classes using <code>\addtogroup</code> tag. After this, I have got a module tab in my documentation. It shows all modules. I want to add some description right below module name below the module name on the same page. How can I do it using Doxygen ?</p>
  
  <p>Here's my tag </p>
  
  <pre><code>/*! \addtogroup test test
   *  Test Testing a group in doxygen
   *  @{
   */
  </code></pre>
