Where do I start if I am interested in designing a cape?

I found the repos with the PCB design materials and many posts about cape projects. I have the knowledge and skill to just grab one of these repos and get to work but I’m looking to see if there is some official starting point.

Thanks

Hello, any one here?

There are some examples here… GitHub - beagleboard/capes: Official BeagleBoard.org capes Go Wild…

Great, thanks!
