Payson provides an Installation Guide that simplifies the installation and the module is easily downloaded through Magento Connect or via Payson’s GitHub page.
The module is developed by Payson and can also be compatible with other versions than those who is recommended, but it is not something we can guarantee or support . Payson recommends to always have the latest module version installed for optimal performance and support.
