-## Prerequisites:
-* [Install ddev](https://ddev.readthedocs.io/en/latest/users/install/ddev-installation/) if you haven't already.
-* Enable ddev on your local Drupal project.
-* Ensure you can already run functional JavaScript tests in the ddev environment. This requires a working chromedriver container as part of your ddev installation. You can run any core functional javascript test without having Gander installed to confirm.
-
-For most use cases, this chrome image should work out of the box:
-```ddev get ddev/ddev-selenium-standalone-chrome```
-
 ## Getting started
-Add Gander and run Drupal's performance tests via Drupal core (assuming [composer is 
-used](https://www.drupal.org/docs/develop/using-composer/manage-dependencies)):
-* `ddev get tag1consulting/ddev-gander`
-* `ddev restart`
-* `ddev ssh`
-* `cd web/`
-* To run a single test three times in order to check the Gander installation, ensure you're in the document root first: `for run in 1..3; do ../vendor/bin/phpunit -c core profiles/demo_umami/tests/src/FunctionalJavascript/OpenTelemetryNodePagePerformanceTest.php --filter hot; done;`
-* To run all OpenTelemetry tests: `../vendor/bin/phpunit -c core --group OpenTelemetry`
-* Check the Grafana dashboard via: _http://\<projectname\>.ddev.site:3000/_
