Abstract
We outline the determination of the weight enumerator of the code of the projective plane of order 5 by hand. The main tools used are a version of Gleason's theorem on the enumerators of self-dual codes and geometric descriptions of codewords of low weight. This paper is in part a condensation of the companion paper (Nota di Mat.) that contains full details.
