I've been given instructions to run go get <some-remote-git-repo> which seems to succeed, but it's not clear to me where the package was installed to so I can run an executable from it.
Per https://golang.org/doc/code.html#remote it seems it will be installed in $GOPATH/bin but $GOPATH isn't defined in my shell (though the go get command seems to work fine). Go is installed via Homebrew.
