+# PROJECT NUMBER 1 - ALGORITHMS & PROGRAMATION I
+
+This folder contains the first project of "algoritmos y
+programacion I" a subject from Facultad de Ingenieria de la
+Universidad de Buenos Aires. The project is a program that
+runs on CLI which its function is to process data entered via
+a .csv file.
+
+What it does is receive a number for a country, date, and number of
+cases (of COVID19), and prints it on stdout with a human readable
+format.
+
+Bibliography:
+
+"The C programming language" - Brian W. Kernighan & Dennis Ritchie.
+
+NAME
+ analisis_covid - analyze RAW data and export it with a human
+ readable format.
+
+SYNOPSIS
+ analisis_covid [-in] SOURCE [-out] DEST
+ analisis_covid [-out] DEST [-in] SOURCE
+
+DESCRIPTION
+ Process RAW data from a .csv(comma separated values) file,
+ and export it to another .csv file, if the output file doesn't
+ exist then it creates one with the specified name.
+
+ When you invoke analisis_covid, expects.. to be continued
