+# O-RAN-SC Hello World Xapp in Python
+
+This repository contains open-source code for a prototype python xAPP for near real-time
+RAN Intelligent Controller which makes use of python Xapp Framework.
+
+This xAPP aims to provide basic implementation of :
+
+1. A1 interfaces interactions
+
+2. Read-write operations into a persistent storage.
+
+3. xAPP Configuration management
+
+4. RMR Health Check
+
+5. xAPP SDL Check
+
+6. Raising alarms
+
+7. Generating metrics (TBD)
+
+8. E2 Interface intereactions (TBD)
+
+
+Introduction
+------------
+
+This document provides guidelines on how to install and configure the HW Python xAPP in various environments/operating modes.
+The audience of this document is assumed to have good knowledge in RIC Platform.
+
+
+Preface
+-------
+This xAPP can be run directly as a Linux binary, as a docker image, or in a pod in a Kubernetes environment. The first
+two can be used for dev testing. The last option is how an xAPP is deployed in the RAN Intelligent Controller environment.
+This covers all three methods.
+
+1. Docker
+
+2. Linux Binary
+
+3. Kubernetes
+
+
+
+Software Installation and Deployment
+------------------------------------
+The build process assumes a Linux environment with python >= 3.8 and has been tested on Ubuntu. For building docker images,
+the Docker environment must be present in the system.
+
+
+##Build Process
+
+The HW xAPP can be either tested as a Linux binary or as a docker image.
+ 1. **Linux binary**:
+ TBD
+
+ 2. **Docker Image**: From the root of the repository, run *docker --no-cache build -t <image-name> ./* .
+
+
+##Deployment
+
+**Invoking xAPP docker container directly** (not in RIC Kubernetes env.):
+ One can include the pod.yaml for including it in k8s build. Replace the image name with one built.
+ TBD: Adding hw-python to nexus repo
+
+
+Testing
+--------
+
+Unit tests TBD

+HelloWorld xAPP (Python)
+============================================================================================
+--------------------------------------------------------------------------------------------
+User's Guide
+--------------------------------------------------------------------------------------------
+
+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.
