 Cobra supports grouping of available commands in the help output.  To group commands, each group must be explicitly
 defined using `AddGroup()` on the parent command.  Then a subcommand can be added to a group using the `GroupID` element
 of that subcommand. The groups will appear in the help output in the same order as they are defined using different
-calls to `AddGroup()`.  If you use the generated `help` or `completion` commands, you can set their group ids using
+calls to `AddGroup()`. To remove added groups you can use `RemoveGroup(groupID string)`. If you use the generated `help` or `completion` commands, you can set their group ids using
 `SetHelpCommandGroupId()` and `SetCompletionCommandGroupId()` on the root command, respectively.
