6. Apply the changes and close the Sprite Editor
7. In the Project Window, expand the Sprite Sheet (arrow next to the imported Sprite)
8. Select at least 2 sheet pieces and drag them into the Hierarchy
9. Create a new animation when prompted 
10. In the Hierarchy, create a new Raw Image Game Object (Left click > UI > Raw Image)
11. Add an Animator Component to the Raw Image Game Object
12. For the Raw Image Animator Component, set the controller as the animation created in Step 9
13. In the Project Window, double click to open the animation created in Step 9
14. Ensure the Raw Image GameObject is selected in the Hierarchy
15. In the Animation window, click on Add Property > Raw Image > Texture
16. Select the keyframes in the Sprite Property (not Texture!) and copy them
