+## `renovate-image`
+
+The Renovate docker image name to use.
+If omited or `renovate-image === ''` the action will use the `renovate/renovate` docker image name otherwise.
+If a docker image name is defined, the action will use that name to pull the image.
+
+This sample will use `myproxyhub.domain.com/renovate/renovate:slim` image.

 ## `useSlim`
 
 If set to `false` the action will use the full renovate image instead of the slim image.
