Thank you for the PR! It looks good!

I know it is a bit silly, what with the changes only being documentation, but could you nonetheless perchance merge main into your branch so the CI goes green before merging?

Not silly at all, I have never understood git, and my work is based on cheatsheets other OSS contributers have given me.

I assume the conflicts were with the clippy commit.

Rebased (I think) on NLnetLabs:main , and pushed again.

Thank you, and to the NLnet/NLNog team, for all your wonderful projects
