 It uses the [Connexion](https://github.com/zalando/connexion) library on top of Flask.
 It propagates requests to the [Sunrise 6G OP service resource manager](https://github.com/OpenOperatorPlatform/service_resource_manager), as configured in the `.env`.
 
+OEG implements the **Northbound CAMARA APIs** for application providers to interact with different infrastructures, including:
+
+- Application metadata lifecycle management (registering, retrieving, deleting apps)
+- Application instantiation management (instantation, and termination)
+- Federation Management APIs to onboard applications accross partners' operator platforms
+
+OEG acts as a middleware layer between the CAMARA APIs and the Service Resource Manager (SRM), by enabling a common exposure of heteregeneous infrastructure resources.
