Find Peerio in Chrome
Peerio for Chrome works a bit differently than traditional applications. Instead of being added to your desktop or applications folder, the application is added to the "apps" tab of your Chrome browser. You can find Peerio by clicking the "apps" button below the "back" button in your browser.
Make a desktop shortcut
If you would like to access Peerio directly from your desktop, simply right click the Peerio icon and click "Create shortcut..."
Chrome will ask you where you want to create the shortcut. Review the options and then click "create".
