This paper gives an exposition of the proof of the zero-divisor conjecture for group rings of polycyclic-by-finite groups. This was proved by the reviewer and D. R. Farkas in characteristic 0 [J. Algebra 42, 192-198 (1976; Zbl 0355.16004)] and in characteristic $$p>0$$ by G. H. Cliff [Can. J. Math. 32, 596-602 (1980; Zbl 0439.16011)]. The exposition follows the original proofs.
