+
+As long as all players are running it, the tracker also fully supports coop. This is done by
+transmitting some information using the item's loot beam, hence the blinking. Coop support can be
+disabled if you find the blinking distracting.
+
+There a few slight caveats to playing in coop:
+
+- In Coopetition mode, each player must individually look at the item to redeem it for themselves,
+  one player can't just unlock it for everyone.
+
+- If any player picks the item up, it no longer counts as a valid drop for the others. Make sure
+  everyone's redeemed it before doing so.
+
+- If players split up, sometimes clients won't get notified of a drop if they're too far away from
+  it. If they then travel back to it, they'll be unable to redeem it.
+
+If you have a particularly bad connection (primarily concering packet loss), you may also need to up
+the blink duration in settings to consistently transmit information to clients.
