-
-2. Change or remove the banner image in the lower part of this readme. Don't worry, a banner image isn't required.
-
-3. Change the example from `"ghcr.io/octocat/features/i-am-awesome:1": {}` to your own name and feature name.
-
-4. Change any of the other readme text to match your own new awesome feature. 🚀
-
-5. Remove the top part of this `README.md` file. You don't want this template guide showing up on your own awesome feature, do you? 😉
