I am new to Magento(2) and I didn't find any good explanation in the docs of how a metapackage works.
My goal is to have the metapackage installed from the Web Setup Wizard and all my shared packages along (3-4 of them).
In one of this shared packages I have dependencies to an open source project (let's say one from packagist).
Now, my question is: when I install the metapackage will this dependency be downloaded & installed in the magento vendor folder or not? should I package this project in my shared package under vendor?
