https://symfony.com/doc/current/bundles.html#bundle-directory-structure

That page is missing a lot of information, so that you can't make your own bundle just reading it.

E.g.:

• The bundle have to be in a /bundles directory
• Some config has to be made in the main composer.json
• Indicated composer.json config is aimed toward bundle's composer.json

As a more general issue, eveything is said to how to structure the bundle itself... But nothing on how to integrate it into Symfony.

I'm guessing that's a problem.

Unfortunately I don't think I have enough expertise on that subject to change the docs (I only managed to make one work and that's already a few hours of step debugging and AI help)
