As Magento 2 Supports composer based installations run the following commands from your magento root directory
composer require styla/magento2-connect
After a successful installation you must enable the module with:
php bin/magento module:enable Styla_Connect2
Finally make sure everything is up to date with:
php bin/magento setup:upgrade
Now, before you can start using your magazine - you must run the "Connection Assistant", available in the Styla Connect section of Magento configuration page. More information is available here: Configuration
