The Zotero Desktop Application allows you to locally edit, import, and manage your Zotero bibliographic library. If you have the Zotero Connector installed, you can also easily import web-based sources!
Zotero runs as a separate program instead of part of your web browser, and works with Windows, macOS, and Linux. Zotero 5 is downloaded and installed like other computer applications.

To utilize the features in Microsoft Word and Google Docs, you will need to download the Zotero plug-ins. Instructions are given on Zotero's Word Processor Plug-Ins documentation page.
