Have you never had a preset before? Alrighty, I'll explain.
When you download the .zip file, open up your feralheart folder. Open My_Presets, then drag the preset_2 folder from the .zip to My_Presets. It'll ask you if you want to replace the files. Click "Replace All". Now when that's done open up FeralHeart. Go to Preset Maker, change the model to canine, then go to the last tab then click preset_2. It should appear on the canine model. Now click export, then send that file, which should say xxchronaxx_2.fhp, to everyone you want to be able to see your preset.
Done :3
