godoc, same problem with any language that uses any kind of modules, you need to consult the documentation for that module. https://pkg.go.dev/github.com/prometheus/client_golang/prome... .. if fount that by googling `godoc prometheus newgaugevec` .. or you could just use `godoc`

Your argument seems to be, "I don't like reading documentation." Then by all means don't and write your own prometheus metrics module shrug
