# Installation You can find an official release archive from the [release page](https://github.com/systopia/de.systopia.twingle). 1. First, download and then unpack the archive and move the directory into your CiviCRM extensions folder (e.g.,`.../civicrm/ext/`. If you don't know where your extensions folder is, just have a look in your CiviCRM settings ( **Administer**/**System Settings**/**Directories**)). 2. Next, open the extensions page in the CiviCRM settings (**Administer**/* *System Settings**/**Extensions**). 3. Find the extension Twingle API in the*Extensions*tab and click on**Install**. The extension will be set up. ## Extended Contact Matcher (XCM) Please note that for the correct working of Twingle API you still need to install the extension Extended Contact Matcher (XCM), see the [documentation](https://docs.civicrm.org/xcm).
