How to play
Gaïa doesn't come with it's own graphical user interface (GUI). You can play online or use a third-party UCI user interface: Arena and Jose are the most common free GUI for UCI chess engines, Chessbase products like Fritz can also be used. They display a chessboard on the screen, accept moves made with the mouse, load and save games in Portable Game Notation (PGN). Currently the program supports the UCI protocol and works under Unix or Windows systems.
