+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)

+
+Using command lines options needs to be done manually for each workflow which you require the option enabled. So for example signing commits requires you to import the gpg signature each and every time. The following list of actions are worth checking out if you need to automate these tasks regularly.
