Started out as a template repository but as I learn more it keeps morphing. Currently it's a list of skills and what they are used for:
Designed to ask questions and help focus the start of an idea into something complete.
You have the idea now you need to firm up what the product will look like
Take that PRD and turn it into a demo so you can continue to iterate
You have the plan and look; now what do you build it on?
The product is defined; turn it into developable chunks
