Integrate the documentation as markdown files on GitHub

Would be great to have the docs in this repo too.

Maybe I can start with a PR?

If you feel like it, sure.

@erikdarlingdata Thanks for assigning me here, but I'm not sure, if @bakirp would be a better fit here because of the work that is already done with PR #36?

If it doesn't get merged, it would be cool to have some requirements for the documention. (e.g. is it a requirement to have the documentation on the website too - Generate it from markdown and push it online - CI/CD?)
