Joining Shimano chain with pin - which link-type should "lead" (take the power)
The way they've worded and shown this in diagrams has always been a little nutty. You can pretty much see what they mean if you max zoom on the full res pdf though.

You are looking at the drive side of the bike. You are holding the chain stretched end to end between your hands. Your left hand holds the end that terminates in an inner link, your right one with an outer link. Put the outer link end on the crank and through the front derailleur as applicable. Put the inner link end through the rear derailleur. Do your sizing on the inner link end such that you're still left with an inner link when done. Then connect it all with the one-time pin.
