+### Overriding steps
+
+The default pipelines use the default [Jenkins X Catalog](/v3/develop/pipelines/catalog/) and so the details of the steps such as the container image and commands used are often inherited.
+
+You can override steps locally by:
+
+* [Overriding a pipeilne step locally](/v3/develop/pipelines/catalog/#overriding-a-pipeline-step-locally) so that you inline the step details into your local YAML file and then edit accordingly.
+* [Override a specific step property locally such as the script property](/v3/develop/pipelines/catalog/#overriding-specific-properties-of-a-step-locally) which lets you just inline, say, the `script` commands to modify the commands run
