Installing "SketchUp-ruby-api-tutorials" with Extension Manager?

Since I don’t know where to go…I’ll start here?
MacOS: Big Sur
MacBook Pro 15’
~/Library is Visible (Apparently MacOS hides this by Default)
Cloned git repository for “example” tutorials
The example files are to be manually entered in the Plugin directory.

Question: How to create “.rbz” file recognizable by Extension Manager to install these examples?

I assume a “developer”…which I’m not…would have cleverly linked in a LOAD_PATH to be searched for installation by Extension Manager?

Brute force approach is to “Zip” the “root” with the “main folder” and rename extension from .zip to .rbz and point the Extension Manager to the file. What’s Right or Wrong with that…It seems to work?

You can manually drag the .rb file and the same named folder into here:

~/Library/Application Support/SketchUp 2021/SketchUp/Plugins

You can get to that folder by choosing Go to Folder from the Finder’s Go menu, and paste in the text I gave.

Putting the .rb and the folder into the Plugins folder is the same as if you had made a zip file, renamed it to .rbz, and used Extension Manager as a way to unzip the rbz into the Plugins folder. You end up in the same state with less steps.

Nice…Thank You
