Is that the prompt you would use, or is there more to it?

The wireguard docs are pretty good, and it's probably worth it at least a little to actually understand what it does.

Actually I wish they would be a lot more verbose and explain the details a little bit better.

Yep and the LLM can help explain, but it is actually super straightforward. Public key cryptography and the text file configs are tiny.

You could try with that as a prompt. I have a repo set up with all of my sysadmin scripts and so the LLM had that as additional context.
