Add how to install with composer under installs

What do you suggest?

As more and more people are using composer, it might be useful to add the composer command to require the extension directly in the first option in install section.

E.g.

How to install with composer:

$ composer require vendor/extension-name

Why?

This being auto generated from the composer.json so that it's extremely easy to add without having to lookup vendor and packages name in composer.json or satis yourself.

Of course some people go directly to composer.typo3.org with is perfectly fine, but those who don't should in my opinion be advised to use composer as FIRST install option.

Add an use case!
