Is there a command like tldr for linux folder heirarchy? - eviltoast

I’m kinda a newbie to linux (…going on 20 years now, slow learner). I recently came across tldr and don’t know how I lived without it, because man pages can be a little much for a non technical person.

Is there a helpfile / command to learn the purpose of the current root directory you are in? I’ve been reading a few books on Linux at the library, and everything about it kinda fascinates me, and I can’t stop asking questions trying to learn about it…

My current question is what is /etc/skel/ . It’s an empty directory and it has some purpose. Is there a tool to query what the purpose of this directory is? Like whatis . or something like that, for educational purposes; rather than having to web search/“google” it everytime.
