Script path for plugin made with rhino command

I’m interested in creating a few rhinocommand scripts to create a plugin
This link explains the process clearly

on creating the _cmd.py file the plugin folder is saved in my python-plugins folder as expected. However i’m unsure of how to link the scripts and make rhino find them. In my case i have my scripts that i need to import to my __cmd.py file in a separate environment.

should I set a python path ?
