You can install Woodpecker from directly within Microsoft Word if you like. To do so, navigate to the "Insert" tab, click "Get add-ins", and then click "Store".
What you're viewing at this point is Microsoft AppSource (the Microsoft app store for Office products).
Type in "Woodpecker" in the search bar and click the "Add" button. Woodpecker will be automatically installed for you and the "Woodpecker Automation" button will be added to your ribbon underneath the "Home" tab.
