How to run pkg.go.dev locally as a godoc replacement?

godoc has been removed from the go standard install since 1.12 and looks like it wont be updated anytime soon. pkg.go.dev at least appears to be its successor. It also has additional documentation features like grabbing the README.md file and rendering it in the documentation page.

For these reasons I was hoping to switch over to using pkg.go.dev locally to view and create documentation for small internal packages. The major issue is that unlike godoc there does not seem to be a clear usage guide. I also do not know if pkpg.go.dev is completely overkill for this task. So I would like to know:

1. Can and should pkg.go.dev be used as a local godoc replacement?
2. If yes, how would I run it for this task?

Run pkgsite locally.

go install golang.org/x/pkgsite/cmd/pkgsite@latest && pkgsite
