 ## Usage
 
-Add the following step at the end of your job, after other steps that might add or change files.
+Adding git-auto-commit to your Workflow only takes a couple lines of code.
+
+1. Set the `contents`-permission of the default GITHUB_TOKEN to `true`. (Required to push new commits to the repository)
+2. Add the following step at the end of your job, after other steps that might add or change files.
 
 ```yaml
