-OAI-CN5G VPP-UPF, as a part of OAI-CN 5G, is an 3GPP-compliant implementation of the Access and Mobility Management Function (AMF). 
+OAI-CN5G VPP-UPF, is a based project of (Travelping VPP-UPG)[https://github.com/travelping/upg-vpp]. OAI added following features on top of VPP-UPG -
+* NF Registration
+* GTPU extension header support
+* Traffic steering based on forwarding policy
+* Build instruction for docker and podman
 
 This wiki provides information to build and launch VPP-UPF manually in a physical/virtual machine. We highly recommend that you follow the [container-based tutorial](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-fed) to have a better tested/supported deployment environment from our team.
