Как установить образец-модуль Magento2 с помощью композитора?

Я использую Magento 2 EE на моей локальной машине. Я искал несколько часов на этом. Я хочу установить образец страницы модуля, указанный здесь:

https://github.com/magento/magento2-samples/tree/master/sample-module-newpage

Вместо того, чтобы загружать и пытаться обувать все внутри, создавая и загружая файлы и папки, я прочитал эту цитату на странице:

This module is intended to be installed using composer.

Я новичок в Composer и мире Grunt и Github, разветвляя и обновляя файлы таким образом; Я старая школа, но пытаюсь адаптироваться.

Как мне это сделать? Мне удалось установить Composer на мою машину, и у меня есть Terminal, открытый для папки Magento 2. Могу ли я просто запустить команду github или Composer; Я старался:

#localhost:magento2ee: composer magento/sample-module-newpage

[InvalidArgumentException]
Command "magento/sample-module-newpage" is not defined.

Я тоже пробовал

#localhost:magento2ee: composer require magento/sample-module-newpage



[InvalidArgumentException]
Could not find package magento/sample-module-newpage at any version for your minimum-stability (alpha). Check the package spelling or your minimum-stability

Ниже приведен мой файл composer.json
