Does Makefile need an explanation?

Simple question: can you add a "why use a Makefile" addition to the Makefile section (https://github.com/xrd/advanced-github-oreilly/blob/jpoz/chapter-10-go.asciidoc#makefile). Meaning, is there a benefit to using a Makefile? Make it easier for people who are new to "go" to run these commands, since "make test" is more familiar than "go test" etc.?
