Installing SmartCite in Word 2016:
Open the Word desktop app, with any document or a new blank one.
Click on the “Insert” tab in the top ribbon, then click on “My Add-ins”.
Click on “Store” in the add-in popup, and search for “SmartCite”.
Click the “Add” button to install in your Word app.
After it’s added, you can open SmartCite by clicking the “My Add-ins” button - the SmartCite add-in will be listed under the “My Add-ins” section and and in your "References" menu. Click on it to start using it.
To update an existing citation in your document, click on it so that the citation is activated (gray “highlight”). You will notice it open back up in the right panel. For citations with multiple references, an individual reference can be deleted by clicking on the corresponding X button in the right side panel, followed by the “Update Citation” button. You can also change the order by dragging the grey boxes (ie. "Miller, 2012" , "Braasch, 2016" ) in the desired order. With all changes, for them to take effect, you'll need to click "Update Citation" at the bottom of the panel.
Search in the “Styles” section to update with another citation style anytime.
