 The E2E framework uses Kuttl under the hood. Kuttl is a simple and most importantly static tool that handles applying manifests for running assertions in a namespace it generates for each test.
 
-In order to dynamically generate manifests, Kuttl supports declaring a `TestStep` manifest which includes an option for running scripts. This allows us apply manifests with dynamic values from stdin.
 
-Additionally, helper functions can be invoked in the scripts by creating a Makefile in each test folder that references `../../Makefile` (i.e. `e2e/Makefile`).
+Helper functions can be invoked in the scripts by creating a Makefile in each test folder that references `../../Makefile` (i.e. `e2e/Makefile`) in order to do custom validation.
