Hi @zroubalik ,@JorTurFer,

Could you please review the finalized PR for #1368? The changes you specified in the previous PR #1415 have been implemented here. However, due to an issue with rebasing, I had to close the earlier PR.

Thank you!

Looks good to me! The only point is that we should include it also as part of v2.16 (if you rebase the branch the folder will be there).

There is another question that comes to my mind, maybe we could transform this into a getting started that we place in the getting started section instead of a versioned documentation. WDYT @tomkerkhove @zroubalik ?
Maybe we can do it in a following PR just refactoring a bit this one (which is nice, tbh)

@JorTurFer Included in v2.16 also and file is present in Getting Started Section for v2.15 and v2.16.
