Composer install on Magento 2.1.4

[ddoddsr]

Where do I run the composer command?
When running
composer require sample/module-news:dev-master
in root of magento 2.1.4 folder I get:

Problem 1
    - Installation request for sample/module-news dev-master -> satisfiable by sample/module-news[dev-master].
    - sample/module-news dev-master requires magento/module-backend ~100.2.0 -> no matching package found.

the first command ran fine and i entered the token as needed.
composer config repositories.sample-module-news git [email protected]:tzyganu/Magento2SampleModule.git

It installed manually, What a great extension!
