How do I install a Magento2 sample-module using composer?

Question

I am using Magento 2 EE on my local machine. I have been searching for a few hours on this one. I want to install the sample page module listed here:

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

Rather than upload and try to shoe-horn everything inside by creating and uploading files and folders I read this quote on the page:

This module is intended to be installed using composer.

I am new to Composer and the world of Grunt and Github forking and updating of files this way; I am old school but trying to adapt.

How do I do this? I have managed to install Composer on my machine and I have Terminal open to the folder of Magento 2. Can I just run a github command or Composer command; I tried:

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

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

I also tried

#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  

The below is my composer.json file

Hope this helps. First, have you cloned the samples repo?

If so, then cd to the directory of the sample you want to install and run:

composer install

That should install the module. If you want to install all modules, back up one directory and run composer install.
