This walkthrough which is hyperlinked within the plugin dashboard is from 2015. Google has updated the dashboard since and it looks nothing like the walkthrough for setting up Google API Project.
This is the help text within the plugin dashboard. "You can read more about setting Google API project here under "usage"
If you could please update the walkthrough, that would be great. I haven't done this before with the new google dash updates so I have no idea where to begin. Trying to setup the plugin.
Thanks so much!
