## Introducing LaTeX

LaTeX is a text composition system, oriented to the creation of written documents with high typographic quality. Due to its characteristics and possibilities, it is used especially intensively in the generation of scientific articles and books that include, among other elements, mathematical expressions.

LaTeX consists of a large set of TeX macros, written by Leslie Lamport in 1984, with the intention of facilitating the use of the typesetting language, TEX, created by Donald Knuth. It is widely used for the composition of academic articles, theses and technical books, since the typographic quality of documents produced in LaTeX is considered adequate for the needs of a first-line scientific publisher, many of which already use it.

LaTeX is free software under LPPL license.
