 # Terminal-Sudoku
 ## A simple Sudoku game running in a terminal for the Hackclubs' Summer Of Making 2025
-### Done in 2.5 days (12h) total
-## README: coming soon!
+## Features:
+### -Playing Sudoku in the Terminal
+### -Detecting when you've messed it up (you only have 1 try!)
+### -Settings (via flags):
+#### -stopwatch: Keep track of how much time you needed, saves the best one!
+#### -sudoku_maker: Save your game in a string
+#### -templates: use a saved game ("state code") to apply it to the current game. It's possible to use your own pre-made template (but not really recommended)
+### -Stats, so you can keep track of your victories (and failures) each session
+### -Nice user interface (always a "clean screen" after each step
+### -Written in Rust, so it's pretty performant and lightweight (~1.25mb with the --release flag) and, if anyone wants that (I would wonder), it's pretty memory safe too!
