Chiral Invariance and Low-Energy Pion-Pion Scattering,The foundations of chiral invariance and its relation to current algebra are well-known since a number of years. Several excellent review articles or lecture notes. are available. I recommend them to those among the audience who wish to study the subject in a systematic manner.
