Hi @Aaron-Meyers ,
For 2018.3 and 2019.1, I would say yes. For 2018.2 and prior, less so.
Our documentation is poor for the moment. We are in the process of writing a completely new section in the Unity user manual for 2019.1 release that will guide you through the creation, hosting and ways to share your own custom packages.
In the meantime. You can ask for help here. There is also a bit of information in the Package Manager User manual:
There is also two sticky thread that exposes two features to help you share your own libraries:
- Scoped registries: Setup for scoped registries (private registries)
- Git Packages: Git support on Package Manager
Hope this will help,
Pascal
