+tests that can be flashed onto a device and run. The device is controlled using
+the included RPCs through the python test runner.

-    cd <connectedhomeip>
-    ./scripts/build/build_examples.py --target linux-x64-pw-test-runner build
-    ```
+The python wheels for the runner can be built and installed like this:
 
-The runner will be installed into the venv and python wheels will be packaged in
-the output folder for deploying.
-
-Then the python wheels need to installed using pip3.
-
-    ```
-    pip3 install out/debug/chip_pw_test_runner_wheels/*.whl
-    ```
-
-Other python libraries may need to be installed such as
+    ninja -C out/debug runner
+    pip3 install out/debug/chip_pw_test_runner_wheels/*.whl --force-reinstall
 
-    ```
-    pip3 install pyserial
-    ```
+## Running the Unit Tests
