I found this guide on Leaguecraft.com, and I found it amazing, and so I wanted to share it with you. It is located Here

To sum it up, Start with a Long Sword item Long Sword and a Health Potion item Health Potion. Masteries and runes are described in the guide, however for runes mine are Reds: AS Yellows: Armour Blue: Magic Resist/CDR (building my CDR runes atm) and Quints: Hp. For spells take Smite Smite and Flash Flash. The Long Sword item Long Sword and masteries allow you to jungle much faster than common Cloth Armor item Cloth Armor builds, and you can often keep up with the level that mid is. Something to note is that when on Purple team, it is slightly slower doing this as you grab their Golem for the blue buff, which is on the opposite side of the map as the Dragon. Happy jungling!

P.S. If you do it right, you'll even sometimes have to wait a few seconds for the gold you need for Madred's Razors item Madred's Razors.
