You install your package, then Atom / npm takes care of installing the dependencies.
https://discuss.atom.io/t/load-developing-package/2554/4
When you start Atom, it downloads packages from different directories. When you open it in developer mode, it loads additional packages from ~/.atom/dev/packages , so the first thing to do is move / symbolize your package to this directory.
Then you can go to your new package directory and run atom -d . to create a new atom window in developer mode and automatically add your package as a project directory.
Then you can run apm install to update your dependencies.
