 ## Example: Spinning up the coraza-wasm-filter for manual tests
 
-Once the filter is built, via the commands `mage runExample` and `mage teardownExample` you can spin up and tear down the test environment. Envoy with the coraza-wasm filter will be reachable at `localhost:8080`. The filter is configured with the CRS loaded working in Anomaly Scoring mode. For details and locally tweaking the configuration refer to [@demo-conf](./wasmplugin/rules/coraza-demo.conf) and [@crs-setup-demo-conf](./wasmplugin/rules/crs-setup-demo.conf).

 In order to monitor envoy logs while performing requests you can run:
 
 - Envoy logs: `docker-compose -f ./example/docker-compose.yml logs -f envoy-logs`.
