There are several instances of upstream NOMAD running, like the pre v1 version at NOMAD the current version or the staging development version. Now the issue is that doing a random Google search for something NOMAD related, it seems one has a good chance to end at the old documentation.
This is not such a big issue for the repository itself as there is a warning “You are using an old version of NOMAD. This version can still be used to view data.”, but there is nothing like that for the docs. Specifically I discussed with my colleague NOMAD Oasis and later told him to check the docs and try and it turned out he ended at the old Oasis docs at Operating an OASIS — NOMAD Repository and Archive documentation
Just doing a random “NOMAD Oasis installation” google search here, while the first link is the correct one, already the second one actually leads to the old docs.
I would suggest either to shut down the old docs, or alternatively put a banner there that they are outdated?
