Need to know how to wire these wires going Honeywell Mercury to Nest Gen 3 thermostat

Hello, all, I am replacing an old Honeywell Mercury thermostat with a Nest Gen 3 thermostat, but I am not sure which wires go where since the Nest app told me it could not help me. Any help would be greatly appreciated. A photo is attached. Thanks in advance!
