 This document compiles some notes about  \tkzname{\tkznameofpack}, the initial version of a \code{Lua}  library designed to perform all the necessary calculations for defining objects in Euclidean geometry figures. Your document  must be compiled using Lua\LaTeX.\\ 
 With \pkg{tkz-elements}, definitions and calculations are exclusively conducted using \pkg{Lua}. \\ 
 The primary programming approach offered is oriented towards \code{object programming}, utilizing object classes such as point, line, triangle, circle, and ellipse.  Currently, after the calculations are completed, \pkg{tkz-euclide} or   \pkg{TikZ} is used for drawing purposes.\\
 I discovered Lua and object-oriented programming  while developing this package, so it's highly likely that I've made a few mistakes.   If you'd like to contribute to the development of this package or provide advice on how to proceed, please contact me via email.
