+# Mock NCE Controller
+
+This REST server implements very basic support for the NCE access controller.
+
+The aim of this server is to enable testing IETF Network Slice NBI, NCE driver and NCE service handler.
+
+
+## 1. Install requirements for the Mock NCE controller
+__NOTE__: if you run the Mock NCE 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_nce_ctrl/requirements.in
+```
+
+Run the Mock NCE Controller as follows:
+```bash
+python src/tests/tools/mock_nce_ctrl/MockNCECtrl.py
+```
+
+
+## 2. Run the Mock NCE controller
+Run the Mock NCE Controller as follows:
+```bash
+python src/tests/tools/mock_nce_ctrl/MockNCECtrl.py
+```
