Thanks for the suggestions! I can certainly split the Development Learnings into a separate document. Re: fine-tuning and training from scratch on custom data, I suppose new data would have to be provided in the same format as the VOC dataset (which should be fairly simple to do). Do you think it would be worthwhile to elaborate on this point in the README.md or a separate attached document? I was thinking about making an annotation program for generating custom data (probably just an HTML5/JS thing) if the need arises for me.
