• Go to your Sonic Generations folder which can be found here:
  (Steam Folder)\steamapps\common\sonic generations\
  e.g. C:\Program Files(x86)\Steam\steamapps\common\sonic generations\
  
• Extract all the files from the Sonic GMI download into this folder.
  
• Run SonicGMI.exe.
  
• Click the "Install/Uninstall" button to enable mods.
