How do I declare a custom language pack?

memele

I am trying to follow the documentation here, but I can't seem to get it right - https://docs.flarum.org/extend/language-packs
I know I can install a language pack, but I found so many translations that I would like to update, that a custom language pack would make more sense.

In the documentation I linked above, it says to create a new directory under the locale directory. I'm guessing that's supposed to be under storage/locale?
Do I put the extend.php file in the language folder alongside the .yml files?
Then, in the composer.json section - do I add the language in the composer.json root or under an "extra" keyword?
After I do all that, do I need to enable the new language in the admin panel?

I guess I would appreciate a step by step process for this, because the official documentation doesn't really explain much.

memele best would be to look at existing language packs:

memele all these steps are performed inside the extension folder, not the Flarum root folder. First you must create a new extension using the development setup https://docs.flarum.org/extend/start

I also want to mention Linguist, which you can use to modify an existing language pack without any coding https://discuss.flarum.org/d/7026-linguist-customize-translations-with-ease It's scalable and will work even with hundreds or thousands of customized translations.
