 - Apply your pipeline
 
+Please do not deploy the bootstrap pipeline in the [Concourse repository](https://github.com/ministryofjustice/cloud-platform-terraform-concourse/tree/main/pipelines/manager/main) into your test cluster. It is
+for production level deployment and may trigger false alarms to our Slack Channel.
+
+To ensure an isolated testing environment, please create a new folder on your local machine and start with a simple pipeline. You may use [this link](https://concourse-ci.org/tutorial-hello-world.html) as reference
+to deploy the first pipeline into your test cluster and not the one under `manager/main`.
