Hey there!

You made kinda nice guide, the content is really filled with information but...I think you could add some markup to keywords like items and champions' names ([[doran's shield]] for Doran's Shield) and color for sections or informations that you think are important not to miss (select the text and use the color wheel above the text editor (but don't use either red or purple colors without bold, they are hard to read)).

Anyway, continue the good work, I know this guide will become incredible with some work.
See ya!
