 # Overview
 
-This is a toy chess engine I developed over two weeks as part of my winter break project. It is **UCI-compatible**, and plays at the level of **1467 Elo** on [CCRL](https://computerchess.org.uk/ccrl/404/cgi/engine_details.cgi?match_length=30&print=Details&each_game=1&eng=Emerald%200.2.0%2064-bit#Emerald_0_2_0_64-bit).

 This software **does not** come with a GUI, so if you want to play it you will need to download one from Internet. I recommend [en-croissant](https://github.com/franciscoBSalgueiro/en-croissant).
