Injora 1.0 Beadlock instructions? Noob

Hello, I'm basically brand new in this hobby l. Got these Injora brass beadlocks that came with these tires. Is the tire supposed to go in-between this middle "collar" ring on the front and back? Does the outer "beadlock" ring with the 16 holes in it have the flange, does the flange face inside the tire to help hold the bead in with the flat side facing out? Or does the flanged side with the gold coloring face outside with the flat side against the rim? I'm very confused. I've kind of tried both ways with neither way seeming right? Thanks
