It guides you through installation and wraps the game in Wine and other layers as its own .Application for running on arm or intel macs. Porting Kit has bespoke configurations for compatible games.
Also see https://github.com/Kegworks-App/Kegworks (formerly Wineskin, the upstream tech leveraged by Porting Kit without the bespoke angle) which i've used for various modern games to great effect.
