Actually disregard that comment. I haven't looked at my Docker Hub since they put the auto-builds behind a paywall so some of my images and tags were screwed up and I didn't realize it.

I just finished setting up a local instance of Docker on my pc and corrected some thinks in my dockerfile. I just built a fresh image that I tested on my Pi and it seems to work correctly.

Using the normal pull command that I listed in my readme should work now. I have the image properly tagged as 'latest'.
