I didn't know either, honestly! I only discovered it while trying to learn about what "rootfs" is when I saw that term in the "Getting Started" section of the Firecracker microVM documentation here [0]. That led me to this [1] Debian wiki, which eventually led to me a Debian ramfs wiki here [2]. That wiki contains the link that is attached to this submission. And I totally agree with you on the difficulty of making documentation like this! I recently had to create documentation for a project at work that also required not assuming prior knowledge, and it took multiple revisions for me to get it into a state I was happy with. Doing it for the Linux kernel is certainly much more difficult, but I think that speaks to the skill and dedication of the maintainers who do it!
