Everything I (almost) know on equiangular lines

A set of lines is called {\em equiangular} if the angle between each pair is the same. We present a brief overview of the study of such a set of lines in the last 60 years. We also give the important properties of such a structure of lines in a general setting that includes real, complex and quaternionic spaces. There have been many attempts to construct equiangular set of lines. We discuss some of these methods and give a few (numerical and exact) examples.
