+### Thanks
 
-Multi-arch dockerhub images are built using [pyldin601/build-multiarch-on-aws-spots](https://github.com/pyldin601/build-multiarch-on-aws-spots). See [build-multiarch.yml](.github/workflows/build-multiarch.yml) for config. Thanks to [@pyldin601](https://github.com/pyldin601) for making this possible.
