+Grouping Options
+++++++++++++++++
+
 When dealing with many options, it is convenient to group these options for
 better help output.  An :class:`OptionParser` can contain several option groups,
 each of which can contain several options.
 
-Continuing with the parser defined above, adding an :class:`OptionGroup` to a
-parser is easy::
+An option group is obtained using the class :class:`OptionGroup`:
+
+.. class:: OptionGroup(parser, title, description=None)
+
+   where
+
+   * parser is the :class:`OptionParser` instance the group will be insterted in
+     to
+   * title is the group title
+   * description, optional, is a long description of the group
+
+:class:`OptionGroup` inherits from :class:`OptionContainer` (like
+:class:`OptionParser`) and so the :meth:`add_option` method can be used to add
+an option to the group.
+
+Once all the options are declared, using the :class:`OptionParser` method
+:meth:`add_option_group` the group is added to the previously defined parser.
+
+Continuing with the parser defined in the previous section, adding an
+:class:`OptionGroup` to a parser is easy::
 
     group = OptionGroup(parser, "Dangerous Options",
                         "Caution: use these options at your own risk.  "
