A complete scheme for muon production, cooling,acceleration and storage in a collider ring is presented. Parameters for 2 muon colliders are given. Both start with pion production on a Hg target A capture and phase rotation yields bunch trains of both muon signs. 6D cooling reduces the longitudinal emittance until it becomes possible to merge the trains into single bunches, one of each sign. Further cooling in 6D is applied in lattices followed by final linear transverse cooling in 50 T solenoids. Experiments suggest that there are rf breakdown problems with the focusing magnetic fields. Possible solutions are discussed.
