 ### Credentials for Zotero access
 
 Zowie relies on the [Zotero sync API](https://www.zotero.org/support/dev/web_api/v3/start) to get information about your references. If you do not already have a [Zotero sync account](https://www.zotero.org/support/sync), it will be necessary to create one before going any further.
