Where do I download Zotero?
You can download Zotero on the Zotero download page. Be sure to also install a Zotero Connector for your browser.
How do I install Zotero?
Open the .dmg you downloaded and drag Zotero to the Applications folder. You can then run Zotero from Spotlight, Launchpad, or the Applications folder and add it to your Dock like any other program.
After installing Zotero, you can eject and delete the .dmg file.
Run the setup program you downloaded.
Download the tarball, extract the contents and run
zotero from that directory to start Zotero.
For Ubuntu, the tarball includes a .desktop file that can be used to add Zotero to the launcher. Move the extracted directory to a location of your choice (e.g.,
/opt/zotero), run the
set_launcher_icon script from a terminal to update the .desktop file for that location, and symlink
ln -s /opt/zotero/zotero.desktop ~/.local/share/applications/zotero.desktop). Zotero should then appear either in your launcher or in the applications list when click the grid icon (“Show Applications”), from which you can drag it to the launcher.
A longtime community member maintains zotero-deb, a lightweight wrapper for the official tarball.
Unofficial packages are also available for various distros, but note that such packages are built by third parties, and we can only provide support for the official tarball and zotero-deb. In particular, third-party packages may be sandboxed, breaking various functionality.
To set up Zotero on a Chromebook, see Installing on a Chromebook.
How do I upgrade to a new version?
Zotero should update itself automatically by default, or you can go to the Help menu and select “Check for Updates…” to check for updates manually. You can also always manually install a new version of Zotero over your existing version without losing any data.
