registering custom maven archetype

How can I register my own Maven archetype, co that other people (in the whole world or just in my local company) might use it?

In Python, there is PyPI, a global registry where you create packages, upload them, upgrade, ... and you've got a user there which you use to authorize your self.

In node.js, there is npm, which works exactly the same. There is also bower, which is similar (though it relies on git branches).

Anyway, this tutorial describes that I can install an archetype locally. But how can I make it public, so that other people may download it? How is it integrated with IDEs (Eclipse, NetBeans, etc.)?
