To install mods, open GMM, select the mods you want to be installed, and hit Patch.
To make one available to GMM, simply drag it into the /mods folder. You can unzip the archive anywhere and it will (hopefully) auto-detect where FTL is located. GMM is compatible with Windows, Mac OS X, and Linux. No longer do you have to pack and unpack files or swap out each mod you want to use one at a time. Grognak's Mod Manager, or GMM for short, is a program designed to make it easy to install multiple mods at the same time. It is highly recommended that you use SMM instead of GMM, if for no other reason then because GMM is no longer developed.
Slipstream or SMM has fewer bugs, is faster and is required by a few newer mods. Please restore your game to vanilla using GMM, and install Slipstream to install/uninstall mods from now on. NOTE - Grognak's Mod Manager is no longer in development and has been succeded by Slipstream Mod Manager
