The quick solution for Granny is to omit all the steps and download a binary
for her platform from the Releases, which I provide.

Yes, download from the Releases.

and $ go build -ldflags "-s -w" for an optimezed version,
instead of using $ go build.

I normally don't do this, but maybe in the future I will
inlude go.mod and go.sum, so that Granny can just run
the build command.

> It would be nice to have a makefile that sets up the GOPATH and GOROOT in the local directory then runs goget, gomod and build. Trying to configure all of that manually is confusing and error-prone for non-go programmers.

When Granny downloads Go, from the official site, it is explained
there how to set GOPATH and GOROOT. And if Granny likes to compile
for Grandpa and friends, she can use my script, which compiles for
different platforms https://github.com/706f6c6c7578/go-build-all
