+# Pyroscope k6 integration
+
+This example demonstrates Pyroscope's k6 integration. This example requires k6
+to be installed. To install k6, see: https://grafana.com/docs/k6/latest/set-up/install-k6/.
+
+## Running the example
+
+To run the example, use
+
+```
+docker compose up
+```
+
+This will start all the necessary services, including:
+
+- A Pyroscope server (http://localhost:4040)
+- Grafana instance with Explore Profiles and a Pyroscope data source installed (http://localhost:3000)
+- An nginx load balancer for the Rideshare services (http://localhost:5001)
+
+Once Docker Compose is running, use
+
+```
+k6 run load.js
+```
+
+to execute a k6 load test against the Rideshare service.
