+# K6 Example
+
+This repository contains a starting point for running k6 tests in typescript. It uses a publicly hosted endpoint so that anyone with internet access can test out the API themselves and then use this repo as a starting point to continue building their own tests.
+
+## Pre-Reqs
+
+- Download `k6` from here https://k6.io/docs/get-started/installation/
+- Install dependencies `yarn install`
+- Docker
+
+### Installing xk6-dashboard with Docker
+
+[xk6-dashboard](https://github.com/grafana/xk6-dashboard) is a k6 extension that can be used to visualise your performance test in real time.
+
+To run the tests with monitoring with xk6-dashboard extension, we need to install it. The simplest way to install is via docker and can be done via
+
+`docker pull ghcr.io/grafana/xk6-dashboard:0.6.1`
+
+## Tests
+
+### reqres
+
+We use the [reqres](https://reqres.in/) publicly hosted REST API to showcase the testing with k6
+
+To execute the first sample test that showcases how `per-vu-iterations` works, you can run:
+
+`yarn test:demo`
+
+To test with monitoring in place, run:
+
+`yarn test-with-monitoring:demo`
+
+To execute the second sample test that showcases how to use `stages`, you can run:
+
+`yarn test:demo-stages`
+
+To test with monitoring in place, run:
+
+`yarn test-with-monitoring:demo-stages`
+
