As Neoku said, Unity Learn is a great place to start place to start learning. When I was just starting out I also used this tutorial series, parts of them guide you through creating a 2D Mario style platformer and also a 3D one. If you aren't familiar with Unity at all I'd recommend not jumping straight to that part though, first either work on the earlier parts of that tutorial series or go through the Unity Learn videos (or both, better yet). Good luck with your game.

@Heu I misread your name as Hue, which seemed more appropriate for that newbie pwn.

 

Use the forum search, the details of the mechanics of Super Mario have been discussed many times here.
