Is there a well documented version of Linux? Coming from a windows user since childhood.

Ubuntu

"Best Wiki Award" goes to Arch Linux

"Best Handbook Award" goes to Gentoo Linux.

But those two aren't the ideal choice for Windows users, as both have a rather steep learning curve.

I'd therefore second Ubuntu. Or, if you want the real soft option, Linux Mint.

Fedora and OpenSuse both have great documentation.

Ubunti & Fedora have pretty solid documentation.OpenSUSE as well. So does Debian and Arch albeit they are a bit harder to use. Won't even recommend Gentoo since it will make a Linux newcomer feel lots of frustration.

If you wanna have something more familiar, try Zorin

It was basically designed to look and feel like Windows

How's elementary OS?

Also no matter where you decide to start, don't let yourself give way to feeling overwhelmed. There are going to be new concepts, but in time things will make sense. Maybe start with Mint (Cinnamon) coming from Windows. ✌️

Elementary or Mint.
Ubuntu in third.

@EclipseMain oh, you are mean! *tehehe* 😈
