 * Unaware of draw by repetition.
 * Basic evaluation includes only material and piece-square values.
 
+#### Usage
+* Use 'make' to build the program as is. This program gives you access to the UCI implementation. 
+* When implementing your own programs, you can create objects of the different parts.
+..* For example, if you need to create a board you can use 'Board board;'
+..* Then you can use the functions in board.c such as 'board_print(&boar);'

+###2PlayerNoFeatures
+As the name suggests, this implemntation is of a chess game with 2 players but with absolutely no features. That means, the users have to account for everything including castling, checkmates, promotions, captures etc.
+
+It is inteded to give you a basic understanding of how to use the library in an actual program. 
+
+####Usage
+Navigate into the examples folder. Then, in your command line, use the 'make' command to build the program.
