The installation instructions in the README specifies using:

go install golang.org/x/tools/cmd/present

However this errors out with the following output:

$ go install golang.org/x/tools/cmd/present
no required module provides package golang.org/x/tools/cmd/present; to add it:
        go get golang.org/x/tools/cmd/present

However running go get succeeds, and then ./presentation.sh works as expected

If you think this is valid, I am more than happy to submit a PR for the same.
