 ### Custom package repositories
 
-If you want to add custom package repositories to your image, you can include them in the `recipe.yml` as a list of URLs under the `extrarepos:` section. They **must** be proper `.repo` files (like `https://copr.fedorainfracloud.org/coprs/atim/starship/repo/fedora-37/atim-starship-fedora-37.repo`). In the build process, the `.repo` file will be downloaded and placed inside `/etc/yum.repos.d/` where rpm-ostree can access it.

 You can use this to add [COPR repositories](https://copr.fedorainfracloud.org/) to your image.
 COPR is like the Arch User Repository for Fedora, where you can find extra packages that wouldn't otherwise be available. The repositories are community-created, so use them at your own risk. [Read more](https://docs.pagure.org/copr.copr/user_documentation.html)
