Pending imba/imba#746 and imba/imba#747

Sounds good, npm link section should be removed imo since it doesn't work "in practice".

Interop is a bit more than including a tag. Communicating back and forth with the other framework is a natural question to ask after including the imba tag.

Great start here. This is a much needed section in the docs 💯

Thanks for taking the time to review and make suggestions earlier by the way Abdellah, really appreciate it.

I would like to make sure these are accurate?

imba is automatically defined on the globalThis object whenever an Imba tag is registered. So as long as you import an Imba file that contains a tag, globalThis.imba will be defined.

as long as an Imba file containing tags gets imported, its custom elements will be registered.

@haikyuu this should be good to go after imba/imba#746, I think it would be good to get it in before ViteConf.
