+This README is for running the tests. See the README in the client
+folder for how the SMO NETCONF client is setup.
+
+The run_tests.sh script 
+1. Brings up simulators(RU & DU)
+2. Brings up SDNR
+3. Add simulators to SDNR
+4. Checks connectivity status by fetching the capabilities
+5. Updates DU and RU config and prints the output
+6. Teardown the services
+
+The environmental variables used to setup and run the simulators is stored in a .env file.
+
+Note: This script should be executed from the root of the repository.
