 ## Architecture
 
 You can use any of the [supported operating systems](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners), and the compatible `architecture` can be selected using `architecture`. Values are `x86`, `x64`, `arm64`, `armv6l`, `armv7l`, `ppc64le`, `s390x` (not all of the architectures are available on all platforms).
