 ## Add a New Chain
 
-To add a chain to the heighliner built-in configuration and have your chain images available on our repository's [ghcr](https://github.com/orgs/strangelove-ventures/packages?repo_name=heighliner), submit a PR adding it to [chains.yaml](./chains.yaml) so it will be included in the automatic builds.
