Doxygen groups and modules index

I am creating a Doxygen document for my project. Recently, I have grouped related cl开发者_如何学Goasses using \addtogroup 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 ?

Here's my tag

/*! \addtogroup test test
 *  Test Testing a group in doxygen
 *  @{
 */

You have to write a dedicated .h file which contains only comments. For each group you define a comment like this:

/** @defgroup FooGroup
 *
 * This module does yada yada yada
 *
 */

Then you assign definition to the group (even on different files) like this:

/** @addtogroup FooGroup */
/*@{*/

/** Summon a goat
 *
 * @param name The name of the goat;
 * @return The summoned goat;
 */
Goat summon_goat (const char *name);

...
...

/*@}*/

EDIT:

Also this is how it becomes. See the "Detailed Description"? You can also add code snippet and examples within the @verbatim and @endverbatim commands.
