How to Train a FLUX LoRA with SimpleTuner

Hello friends! Today we are tackling the lovely world of SimpleTuner. This is an amazing piece of software, always getting support for the latest models first! Sadly it comes at the expense of a GUI and windows support but we are using RunPod for this so it should be smooth sailing.
I've prepared a quick video outlining the process. One issue that came up was that the documentation was a tiny bit outdated based on a commit to the main diffusers branch happening while I was recording, but I figured it out and continued.
