If the chain fell off the rear derailleur, it needs to be re-fed through the proper pulleys.
Feed the chain along the guide pulley (the highest of the two pulleys).
Thread the chain inside the derailleur cage in between the tension and guide pulley.
Thread the chain in front of the tab.
Then, thread the chain over the tension pulley.
