The `ASDF_GOLANG_OVERWRITE_ARCH` variable can be used to override the architecture
that is used for determining which Go build to download. The primary use case is when attempting
to install an older version of Go for use on an Apple M1 computer as Go was not being built for ARM at the time.

#### Without ASDF_GOLANG_OVERWRITE_ARCH

```
> asdf install golang 1.15.8
Platform 'darwin' supported!

## Skipping Checksums

By default we try to verify the checksum of each install but ocassionally [that's not possible](https://github.com/kennyp/asdf-golang/issues/91).
If you need to skip the checksum for some reason just set `ASDF_GOLANG_SKIP_CHECKSUM`.
