```

## Runtime

Environment variables:

Publishing requires a repository Actions secret named `REGISTRY_TOKEN` with package write access for `MrSphay`.

## Notes

Dockge does not currently expose a stable documented plugin API. This repository is structured as a read-only companion service that can run beside Dockge and inspect the same stack directory plus Docker Engine metadata.
