 # rcl_interfaces
-This package contains the messages and services which ROS client libraries will use under the hood to
-communicate higher level concepts such as parameters.
-
-
-## Parameter Groups
-Parameters are contained in groups.
-The default group is '/'.
-It behaves like a filepath, where you can nest sub-groups within groups.
-
-## Standard topics for parameters
-
-The ROS API for a node will be as follows inside the node's namespace.
-
-### Topics:
- * `parameter_events`: `ParameterEvent`
-  * This topic provides a way to subscribe to all parameter updates occuring on the node, including addition removal and changes in value. Every atomic change will be published separately.
- * `parameter_event_descriptors`: `ParameterEventDescriptors`
-  * This topic provides a way to subscribe to all parameter updates occuring on the node, including addition removal and changes in value.
-    Every atomic change will be published separately. This is provided if large parameter values are expected to slow down the system.
-
-### Services:
-
- * `get_parameters`: `GetParameters`
-  * The service to get the value of parameters which are set on this node.
- * `has_parameters`: `HasParameters`
-  * Query this node if specific parameters are set.
- * `list_parameters`: `ListParameters`
-  * List the parameters on this node matching the filters.
- * `set_parameters`: `SetParameters`
-  * Set parameters on this node.
+A set of packages which contain interface files (.msg and .srv) used for the internal implementation and testing of the client libraries.
