 The *etsi_its_messages* package stack allows to use standardized ETSI ITS messages for V2X communication in ROS / ROS 2 systems. Apart from the definition of ROS message equivalents to the ETSI ITS standards, this package stack also includes a conversion node for serializing the messages to and from a UDP payload, as well as RViz plugins for visualization (ROS 2 only).
 
+All message definitions and conversion functions are automatically generated based on the [ASN.1 definitions](https://forge.etsi.org/rep/ITS/asn1) of the standardized ETSI ITS messages.

 ## Concept
 
 ![Framework](assets/framework.png)
 
+The core concept of the *etsi_its_messages* is to automatically generate the ROS support code based on the [ASN.1 definitions](https://forge.etsi.org/rep/ITS/asn1) of the standardized ETSI ITS messages *(CodeGen)*. The ROS support then allows ROS applications to not only natively use corresponding ETSI ITS message types, but to also exchange encoded ETSI ITS message payloads with the world outside of ROS *(Runtime)*.
+
+A given ASN.1 definition is used to generate corresponding C-structures, ROS message definitions, as well as conversion functions between those two formats.
+
+During runtime, the `etsi_its_conversion` ROS node converts incoming UDP payloads into corresponding ROS messages and vice versa. The ROS equivalents of the ETSI ITS messages can be used in any downstream ROS applications or visualized using the provided RViz plugins.
+
