The easiest way to install Woodpecker is to sign into your dashboard and click either "Open in Word for Mac/PC" or "Open in Word Online."
Clicking "Open in Word for Mac/PC" will automatically launch Word on your computer as long as you have it installed (if you don't have Word yet, you can get it with Office 365 here).
Clicking "Open in Word Online" will automatically launch Word Online. You may be prompted to sign in with your Office 365 account.
Regardless of which platform you choose to launch Woodpecker in, the app will get automatically installed and a button will be added to your ribbon underneath the "Home" tab called "Woodpecker Automation."
