-A chess engine
+A chess engine with focus on fast move generation.
+
+## Building
+
+The following dependencies are used for the GUI:
+- gtk 4
+- librsvg (for loading the piece images)
+
+The engine can be built with cmake.
+
+```
+cmake .
+make
+```
+
+If you do not use make, replace it with ninja for example. The build script contains multiple
+targets:
+
+- chess: This is the main target. It has a GUI and the user plays as white. The engine responds with
+  a move for black.
+- chessNoComputer: The user can play both sides in a GUI. Mainly added for testing the move
+  generator.
+- findMagicNumber: finds Magic Numbers for the magic bitboard.
