Control Panel Location:
Developer > Add-Ons
This section of the Control Panel is where add-on functionality is installed, updated, configured, and removed. They can be filtered by status and developer, and sorted by the add-on name and version. This section is divided into to sections, one for add-on functionality included with ExpressionEngine, and one for third party add-ons.
The Add-On Manager will not download and install add-ons for you. In order to install an extension you must first place the add-on package in your
/system/user/addons/ folder and then when you reload the Add-On Manager the add-on will automatically be available for you to install.
Note: Add-ons might require other tasks to function correct, so make sure to follow any instructions included with the add-on.
