Looking better, but since the 'go get' step compiles your main.go and puts it in $GOPATH/bin/go-bootstrap, the instructions could be simpler still:
go get github.com/go-bootstrap/go-bootstrap
$GOPATH/bin/go-bootstrap -dir github.com/$GIT_USER/$PROJECT_NAME
cd $GOPATH/src/github.com/$GIT_USER/$PROJECT_NAME && go run main.go
