+# Mock IETF ACTN SDN Controller
+
+This REST server implements very basic support for the following YANG data models:
+- IETF YANG Data Model for Transport Network Client Signals (draft-ietf-ccamp-client-signal-yang-10)
+  - Ref: https://datatracker.ietf.org/doc/draft-ietf-teas-ietf-network-slice-nbi-yang/
+
+The aim of this server is to enable testing ietf netowrk slice service driver and ietf slice service service handler
+
+
+## 1. Install requirements for the Mock IETF Network Slice SDN controller
+__NOTE__: if you run the Mock IETF Network Slice SDN controller from the PyEnv used for developing on the TeraFlowSDN
+framework and you followed the official steps in
+[Development Guide > Configure Environment > Python](https://labs.etsi.org/rep/tfs/controller/-/wikis/2.-Development-Guide/2.1.-Configure-Environment/2.1.1.-Python),
+all the requirements are already in place. Install them only if you execute it in a separate/standalone environment.
+
+Install the required dependencies as follows:
+```bash
+pip install -r src/tests/tools/mock_ietf_network_slice_sdn_ctrl/requirements.in
+```
+
+Run the Mock IETF Network Slice SDN Controller as follows:
+```bash
+python src/tests/tools/mock_ietf_network_slice_sdn_ctrl/MockIetfNetworkSliceSdnCtrl.py
+```
+
+
+## 2. Run the Mock IETF Network Slice SDN controller
+Run the Mock IETF Network Slice SDN Controller as follows:
+```bash
+python src/tests/tools/mock_ietf_network_slice_sdn_ctrl/MockIetfNetworkSliceSdnCtrl.py
+```
