Similar, at a company they asked the person cataloging the systems to write a yaml, then a dev wrote a script that converted it to html and then they asked a designer to slap some CSS on it. I don’t think it took more than an hour of each person’s time. Plus you can do each stage individually and improve it over time. For example later yet someone put the yaml in a git repo and threw together a simple deploy, someone made a script that pinged systems periodically etc.
