+# Jumpstarter SOC testing with pytest example
+
+This example aims to demonstrate Jumpstarter in an a simple
+SOC testing scenario using pytest.
+
+The following drivers will be utilized:
+- DUTLink: for power, storage and console control of the target
+- UStreamer: with an hdmi capture card plus a webcam for video snapshits
+
+This example requires the following hardware:
+- 1x Raspberry Pi 4
+- 1x dutlink  (DUTLink could be replaced by a composite set of power, storage mux and serial port interface)
+- 1x HDMI Capture card
+- 1x Webcam
+
+# Running the example (distributed env)
+
+1) Setup an environment with the required hardware, and customize the exporter.yaml
+2) Setup the exporter to be run from a container (TODO: link)
+3) Label the exporter in k8s with the `board=rpi4` label
+4) Prepare the images by running `make` in the `image` directory
+5) Run the tests in this directory by running:
+```bash
+$ cd jumpstarter_example_soc_pytest
+$ uv run pytest -s
