INSTRUCTIONS are missing for downloading

I found out about OpenEdX in an article about free LMS platforms. The site doesn’t provide instructions for how to set it up and use it with actionable links for downloading the software. I had to do a separate online search to find an instructional document/page, but it had no links or directions for downloading the application. LOL
It seems to be for people who have already learned such things and do not need instructions. Not sure what to do with this.

You may want to look at the instructions for Tutor

GitHub - overhangio/tutor: The Docker-based Open edX distribution designed for peace of mind

and the documentation for Tutor

Apparently, they do have documentation about installing OpenEdx.
I just do a quick Google search “setup openedx”.
