Tested with docker run.

Thanks! I've published a new version, which includes the use of go modules, making this PR outdated.
Would you mind telling me what a Dockerfile would add as benefit for this repo? I might consider adding it.

Hi @003random,

I think adding a Dockerfile would be a valuable improvement. Not everyone will have Go installed locally, but most developers either already have Docker or can install it easily.

Having a Dockerfile would allow the tool to be built and run consistently across platforms (linux, windows or mac), without requiring users to worry about local installations or dependency management. This would significantly lower the setup barrier and improve portability and adoption.
