Magento Community Edition is open source software and can be downloaded for free. Developers can modify the core code and add features and functionality by installing extensions from the Magento Connect marketplace.
Because Magento does not provide technical support for this software, you can benefit from the knowledge of experts in the community for help with the installation and configuration. Answers to many technical questions can be found on our user forum.
After you verify that your hosting environment meets the system requirements, you can download Magento Community Edition free of charge from the Magento community site. Although optional, we recommend that you register on our site so you have access to the forums, wiki, groups, screencasts, and other resources the community has to offer.
