Linux users
Welcome, friends!
As you no doubt are already aware, Ubuntu is a (Debian-type) GNU/Linux operating system, much like the one(s) you have already used. However, Ubuntu has a strong focus on usability and user-friendliness, which could, depending on your previous distribution, be a very different experience than what you are used to.
We hope that this guide can help you in your transition to Ubuntu, or just to learn about another Linux distribution.
