+## Question
+
+How are PR environments cleaned up?
+
+
+## Answer
+
+We create one namespace per PR. Codefresh intercepts all webhook actions for a PR. We create a pipeline and associate it with the closed action of a PR. This causes the pipeline to execute, which runs a step that deletes all Helm releases for the PR namespace and then deletes the namespace itself.
