The Zotero tab should automatically be added to Microsoft Word and Google Docs when you install Zotero.
Adding a Citation
1. Place your cursor where you want the footnote to go.
2. Select 'Add/Edit Citation'.
3. In the pop-up window, search for the terms of the source you want (name, author, title). When you have found your source, select it.
Updating a Citation
After you update a citation in Zotero, select 'Refresh' to update your document.
Before you submit your assignment, unlink citations, this is irreversible and should only be done on your final version. You can save a draft with your citations linked.
This will allow you to manually edit or change any citations you need.
