OpenCart allows extending functionality through modules. This document discusses uploading, installing, configuring, uninstalling, and removing OpenCart modules. Modules can be uploaded through FTP or the admin panel extension installer. The file structure of module zip files varies by functionality. To install, go to Admin > Extensions > Modules and click the green plus sign. Uninstalling finds the module and clicks the red minus, then refreshes modifications. Removing first uninstalls then deletes all uploaded module files.
