Plugin integration guide

Hi, I'm building Feelback.dev which allows to integrate Like buttons, Emoji reactions, Do you find this page useful? widgets and in general Send feedback forms. In general, some UI stuff to add to your website to receive signals from your users.
I'm planning to make some guide or tutorial to integrate with website builders.

Would like to have some guidance on the how deep the explanation will need to be.

Are NoCode users familiar with the concept of injecting <script> tags or write some markup?
Or it's needed something more trivial, like some wizard or configurator?

I appreciate any help. Thanks.
