-This command is used in order to manage the consumer groups associated with a
-stream data structure. Using `XGROUP` you can:
+This is a container command for stream consumer group management commands.
 
-- Create a new consumer group associated with a stream.
-- Destroy a consumer group.
-- Remove a specific consumer from a consumer group.
-- Set the consumer group _last delivered ID_ to something else.
-
-To create a new consumer group, use the following form:
-
-    XGROUP CREATE mystream consumer-group-name $
-
-The last argument is the ID of the last item in the stream to consider already
-delivered. In the above case we used the special ID '$' (that means: the ID of
-the last item in the stream). In this case the consumers fetching data from that
-consumer group will only see new elements arriving in the stream.
-
-If instead you want consumers to fetch the whole stream history, use zero as the
-starting ID for the consumer group:
-
-    XGROUP CREATE mystream consumer-group-name 0
-
-Of course it is also possible to use any other valid ID. If the specified
-consumer group already exists, the command returns a `-BUSYGROUP` error.
-Otherwise, the operation is performed and a @simple-string-reply `OK` is
-returned. There are no hard limits to the number of consumer groups you can
-associate with a given stream.
-
-If the specified stream doesn't exist when creating a group, an error will be
-returned. You can use the optional `MKSTREAM` subcommand as the last argument
-after the `ID` to automatically create the stream, if it doesn't exist. Note
-that if the stream is created in this way it will have a length of 0:
-
-    XGROUP CREATE mystream consumer-group-name $ MKSTREAM
-
-A consumer group can be destroyed completely by using the following form:
-
-    XGROUP DESTROY mystream consumer-group-name
-
-The consumer group will be destroyed even if there are active consumers and
-pending messages, so make sure to call this command only when really needed.
-This form returns an @integer-reply with the number of destroyed consumer groups
-(0 or 1).
-
-Consumers in a consumer group are auto-created every time a new consumer name is
-mentioned by some command. They can also be explicitly created by using the
-following form:
-
-    XGROUP CREATECONSUMER mystream consumer-group-name myconsumer123
-
-This form returns an @integer-reply with the number of created consumers (0 or
-1).
-
-To just remove a given consumer from a consumer group, the following form is
-used:
-
-    XGROUP DELCONSUMER mystream consumer-group-name myconsumer123
-
-Sometimes it may be useful to remove old consumers since they are no longer
-used. This form returns an @integer-reply with the number of pending messages
-that the consumer had before it was deleted.
-
-Finally it possible to set the next message to deliver using the `SETID`
-subcommand. Normally the next ID is set when the consumer is created, as the
-last argument of `XGROUP CREATE`. However using this form the next ID can be
-modified later without deleting and creating the consumer group again. For
-instance if you want the consumers in a consumer group to re-process all the
-messages in a stream, you may want to set its next ID to 0:
-
-    XGROUP SETID mystream consumer-group-name 0
-
-This form returns a @simple-string-reply `OK` or an error.
-
-Finally to get some help if you don't remember the syntax, use the HELP
-subcommand:
-
-    XGROUP HELP
-
-@history
-
-- `>= 6.2.0`: Supports the `CREATECONSUMER` subcommand.
+To see the list of available commands you can call `XGROUP HELP`.
