Updates to the official Diablo III site are starting to pick up steam! A couple weeks ago, Blizzard introduced the followers that will aid you in the game. Now Blizzard has provided information on the runestones system that will allow you to customize your skills.

There are five runestone types: Crimson, Indigo, Obsidian, Golden, and Alabaster. Each runestone affects skills differently. For example, adding a Crimson Runestone to a skill may enhance its damage, while adding an Alabaster Runestone might add a stun effect. Also, higher ranked runestones will increase the effects.

Head over to the runestones page to see videos that demonstrate how the items can customize various skills in the game.
