 You can observe the tests by using the UI [http://localhost:8080/applications](http://localhost:8080/applications) with username `"admin"` and password `"password"`.
 
 ## Configuration of E2E Tests execution
 
-The Makefile's `start-e2e` target starts instances of ArgoCD on your local machine, of which the most will require a network listener. If for whatever reason you already have network services on your machine listening on the same ports, the e2e tests will not be able to run. You can derive from the defaults by setting the following environment variables before you run `make start-e2e`:
