Zotero Local API Setup

Required: Groundero currently only works with local Zotero. Make sure the local API is enabled:

1. Open Zotero
2. Go to: Settings → Advanced → Config Editor
3. Set extensions.zotero.httpServer.localAPI.enabled to true
4. Restart Zotero

Without this setting, Groundero won't be able to connect to your local Zotero library.
