any documentation about module.json file?

[sprklinginfo]

Hi, I couldn't find information about when/how the module.json is used (apologies if I have omitted it). just saw it is mentioned sparsely here and there in the repo's issues, e.g. 'files' key could be used to load php files in the module's directory.

{
    "name": "Blog",
    "alias": "blog",
    "description": "",
    "keywords": [],
    "priority": 0,
    "providers": [
        "Modules\\TenantAdmin\\Providers\\BlogServiceProvider"
    ],
    "aliases": {},
    "files": [],
    "requires": []
}

So what about other keys, like 'priority' or 'alias' or 'requires'? and for the 'providers' key here, does it have anything to do with provides() function in BlogServiceProvider.php file? thanks!

aliases and requires are no longer used, I think they we're used in older versions.
priority is a way to set a loading order by giving different modules a different number.
I'm not sure if providers is used actually, its generated with the module.
