It's best to use Composer for installation, and you can also find the package on Packagist and GitHub.
To install, simply use the command:
$ composer require baraja-core/heureka-feed
You can use the package manually by creating an instance of the internal classes, or register a DIC extension to link the services directly to the Nette Framework.
