+# Setup and Running Testability Metrics
+
+## Setup Instructions
+
+1. Clone the repository
+
+   - git clone your-repo-url
+   - cd cli-swen777
+
+2. Install dependencies and setup environment
+
+    - make
+
+    The above command will:
+    - Create a virtual environment inside ./venv
+    - Install all dependencies
+    - Install HTTPie in editable mode
+    - Run the test suite once
+
+3. Activate the virtual environment
+
+    - source venv/bin/activate
+
+4. Run the testability metrics script
+
+    - python3 courseProjectCode/Metrics/Testability.py
+
+    The above command will:
+
+    - Run all tests with coverage enabled
+    - Generate a coverage report
+    - Output the total number of test cases and test suites
