You build him similarly to every other ranged AD.
Start boots + 3pots or dblade, first trip back shoot for a total of 2x dblade + berserker's greaves
From there you can either build towards IE + PD or BT + Trinity. IE + PD is more damage, BT + Trinity is more poke + utility.
Grab a LW next, then a defensive item (QSS or GA), and lastly whichever of the BF sword items you didn't build initially.
Same runes as every other AD carry - AD quints, armor pen marks, armor seals, whatever glyphs you feel like.
