Cool @ekatef :)
For me this is fine and I believe no conflicts should appear with #918 : in #918 no changes are (yet) included on that file.
Since you are investigating that PR, do you foresee changes on the opts file?
If not, we can merge this PR

Thanks a lot @davide-f!
As a second thought, #918 is focused on improving explanations for installation and tutorials, which shouldn't go into configtables. So, agree that the conflicts with this PR are not likely 🙂
