+Introduction
+============================================================================================
+
+The RIC platform provides set of functions as part of xAPP Python Framework that the xAPPs can use to accomplish their tasks.
+This xAPP is envisioned to provide python xAPP developers, examples of implementing these sets of functions.
+Note, HW xAPP does not address/implement any RIC Usecases.
+
+HelloWorld xAPP Features
+============================================================================================
+
+RIC Platform provides many Frameworks, APIs and libraries to aid the development of xAPPs. All xAPPs will have some custom
+processing functional logic core to the xApp and some additional non-functional platform related processing using
+these APIs and libraries. This xAPP attempts to show the usage of such additional platform processing using xapp RIC framework APIs and libraries.
+
+
+The Hello World xApp demonstrates how a python based xApp uses the A1, and E2 interfaces and persistent database read-write operations.
