 ParaTest splits your test suite across multiple worker processes. Each worker receives a `TEST_TOKEN` environment variable (`0`, `1`, `2`...) which the package uses to route that worker to its own ChromeDriver instance on a unique port. This means each worker gets a completely independent browser session with no shared state between processes.
 
+## Example project
+
+I've created https://github.com/jackbayliss/dusk-parallel-demo as a demo Laravel project with passing parallel tests if you'd much rather see an example with workflow passing.
