Clarification needed: how can I run spin.js options file detailed on website?

[slferris]

The instructions for spin.js under "Usage" on your website tell me to "Run the following code when the document has loaded:". I'm still new to javascript, so how and where do I do that in my project?

I tried placing the options code for the spinner from your website in my html, but it didn't work there. I also attempted to use a module with a script tag, but that doesn't work either. In both cases VS didn't like the "import {Spinner} from 'spin.js';" statement in the first line. I thought I needed to change 'spin.js' to './spin,js', but that didn't work either.
