If we did a good job then the paper should be written in a way that is digestible. When you don't understand things, follow the references to learn more (and there's probably videos covering most of the components we use).

In the Appendix we have a case study that should be possible to re-implement and run with a single GPU/TPU. We are hoping the community can build from that and innovate. If you take these steps and get stuck, feel free to get in touch!
