Magento integration is very easy and can be done quickly with 5centsCDN's architecture. In order to do this, you need to create your Pull Zone and add your CName record. If you have not done this, please refer our article by clicking here. Once you have created your Pull Zone and CName please follow the below steps.
Below is an example considering cdn.domain.com is your CNAME and www.domain.com your origin.
To confirm that the plugin is working view the page source of your website. If your URL paths are showing the CNAME (or CDN URL, depending on what you used), then you have successfully integrated your website with 5centsCDN.
