How to set up automatic synchronization of my library in Zotero?

Automatic synchronization in Zotero enables seamless updates of your reference library, notes, attachments, and metadata across all your devices by connecting to cloud storage. Configuring it requires linking your Zotero account to either Zotero's own online storage or a compatible WebDAV server. Essential prerequisites include creating a free Zotero.org user account. Synchronization requires using Zotero's cloud storage (300MB free, upgrades available) or a personal WebDAV-compatible storage service like Nextcloud, OwnCloud, or Dropbox (though Dropbox's WebDAV support can be unreliable). Sufficient storage quota for your entire library is mandatory. Regularly resolving sync conflicts is recommended to maintain library consistency across devices. Navigate to `Edit` > `Preferences` > `Sync` in the Zotero desktop app. Enter your Zotero account username and password. Under the `Sync` tab, choose either "Zotero Storage" or specify your "WebDAV Server", inputting the server URL and authentication details. Check the boxes for "Sync automatically", "Sync full-text content", and "Sync attachment files in My Library". Click "Set Up Syncing" and "Sync Now". Your library will synchronize continuously in the background.
