I am not a "go" native person. ( on an off topic conversation why did they make go a snap?)

It would appear that this heavily revolves on "go get" for which I receive:

go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'.

What does one do with this? Thanks in advance...
