Thank you for considering phpChess!
Installing phpChess is fairly simple. in short you have to a) a mysql database, b) copy the complete phpChess folder onto your installation location; and c) go to the weblink of your phpchess installation folder and follow the instructions. phpChess has extensive capabilities and we hope this is the first step to your chess web journey.
upgrading phpChess works in the same manner, but instead of going into the /install folder url, select the install/upgrade URL. Before you do always copy all files from the upgrade into the phpchess folder on your (shared) server.
