 # ETSI TeraFlowSDN Controller
 
-[ETSI OpenSource Group for TeraFlowSDN](https://tfs.etsi.org/)
+The [ETSI Software Development Group TeraFlowSDN (SDG TFS)](https://tfs.etsi.org/) is developing an open source cloud native SDN controller enabling smart connectivity services for future networks beyond 5G.
 
-Former, [Teraflow H2020 project](https://teraflow-h2020.eu/) - Secured autonomic traffic management for a Tera of SDN Flows
+The project originated from "[Teraflow H2020 project](https://teraflow-h2020.eu/) - Secured autonomic traffic management for a Tera of SDN Flows", a project funded by the European Union’s Horizon 2020 Research and Innovation programme that finished on 30th June 2023.
