[Wine] Installing Winehq to OS X 10.5.1

[Camsy34]

Hi,
I'm wanting to install Wine to my eMac for one game: Star Sonata. However I don't understand where I go to install it. I've read all the install guides and gone to the download page but it just doesn't make sense, none of the links seem to be for Mac. I don't want to sound stupid posting a how to install wine into the forums but I feel this is the only way. I really need direct instructions on how to install. Thankyou.
