For anyone interested in contributing their apps to use this framework, I added documentation on how to create a packageManifest, a repository, and how to get your repository added to the list. You can find this info at hubitat-packagemanager/README.md at master 路 dcmeglio/hubitat-packagemanager 路 GitHub
Hopefully people buy into this, it'll be kind useless if only 1-2 devs use it
