Adding payment modules
There are two ways of adding Systempay payment modules:
The first method consists in adding the payment module via the WordPress Back Office.
From your WordPress shop administration interface, in the Plugins > Installed Plugins menu, click Add New.
Select Upload Plugin, click Browse and search for the payment module on your hard drive.
Then click the Install now button.
The second method consists in copying the module via FTP. To do this, copy the woo-systempay-payment folder into the /wp-content/plugins/ folder of your website.
Once the module is installed, click Activate to activate the module (Extensions / Installed extensions).
