Hit the download button to download the .zip file. Then you can either double click on the ABR file (the file the brushes are located). Or you can save them, go into photoshop and click the Brush tool on the tool pallet, then right-click on your document window, and a pop up will show up (brush diameter, hardness, brush variants). On the upper right hand of the pop-up, there is a small "play button". Click that. Then click "Load Brushes..." and locate your brush file. I hope this helps!
