 # MirrorRayPath
+> *Read this in other languages: :gb: [English](README.md), :ru: [Русский](README.ru.md)*
+## Description
 Simple visualization of propagation of rays reflected from a mirror
 
-Now includes python scripts for the following cases:
-- A spherical mirror and a collimated beam. There the mirror curvature radius, angle of the collimated beam and number of rays can be changed
-- A sphreical mirror and a beam of a point source. There the mirror curvature radius, point source position, amplitude angle of the beam divergence and number of rays can be changed
+Includes two types of mirrors: spherical and parabolic; and two types of beams: collimated and divergent.
+One can change curvature radius, angle of incidens, number of rays and point source position (for divergent beam).
