This is an old revision of the document!
We’re in the process of updating the documentation for Zotero 5.0. Some documentation may be outdated in the meantime. Thanks for your understanding.
What version of Zotero do I have?
You can check your Zotero version by selecting About Zotero from the Zotero menu (Mac) or Help menu (Windows/Linux). Make sure you have the latest version listed on the changelog.
You can upgrade to the latest version of Zotero via Help → “Check for Updates…” within Zotero or, if that's not working correctly, from the download page.
