Hi,

I marked the PR as draft. feel free to request a review once you are ready.

I was wondering if I should add something about more advanced setups, but I think that might be overdoing it. There is enough information here to help people get started, and the rest of the information is better found in the K3s docs anyway.

LGTM 👍. You could enable GitHub actions in your repository, so syntax, build, spelling and link checks will be done (which is otherwise the case after merge).

Enabled and fixed a few lint and spellcheck errors. Linkchecker never completes locally, so hoping for better luck on GHA.

Linkchecker never completes locally

I guess it's still liche in your case, right? I just merged the migration to lychee, which is much faster and more reliable. But also not 100%. It's >3000 links checked, and sometimes the worker machine denies/fails at an URL with a timeout then. It's however easy to scroll through the list and verify via browser that the URLs are actually valid.

Things will become again much better with: lycheeverse/lychee#262
All the internal links will be checked via file existence only (currently via locally running webserver), which also allows us to check all files in a single call (currently per-directory, to correctly resolve internal links), which means that duplicate URLs won't be checked multiple times, reducing the overall checked URLs dramatically.

Ah one last thing: It needs to be added to the overview page as well: https://github.com/MichaIng/DietPi-Docs/blob/dev/docs/software.md#system-stats--management

Done!

I'll merge this so we can create a final dev => master PR.
