Magento supports installation of modules by a web-based interface accessible by the administration area of a Magento installation. Modules are hosted on the Magento eCommerce website as a PEAR server. Any community member can upload a module by the website and is made available once confirmed by a member of the Magento team. Modules are installed by entering a module key, available on the module page, into the web based interface.
There are three categories of modules hosted on Magento Connect:
? Core Modules
? Community Modules
? Commercial Modules
Core and Community modules can be installed by the administration area. Commercial module pages give price information and a link to an external website.
