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 Some documentation may be outdated in the meantime.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.
In an effort to make Zotero as user friendly as possible we have developed these screencasts demonstrating many of the basic functions of Zotero. Click on any of the images to watch screencasts detailing the features named below. Special thanks to Steve Bailey from CU-Boulder for preparing the introductory demo.
