 # CORDLE - The C90 Version of Wordle
 
+A C90 implementation of the famous word game Wordle. I originally wrote this 
+in Python, and decided to rewrite it in C90, to remediate myself, and to have 
+a project I could work with in my old copy of DOS TurboC. Feel free to do 
+whatever you like with it.
+
+
 ## Requirements
 
-- C90 compiler (tested with gcc -std=c90)
+- C90 compliant compiler (tested with gcc -std=c90 -pedantic -Wpedantic)
 - Standard C library
 - Ncurses
