Here is a brief guide to using it. You can also import your Zotero citations into Microsoft Word.
First go to REFERENCES on the Tool Bar and Select a Style.
Next add your resources under MANAGE SOURCES
Then when you need to add a citation to your paper go to INSERT CITATION. It will add it to the Footnote if you are doing that style.
Once you are finished and ready to add your bibliography (which is normally towards the end of your paper).
Start a New Page then click on Insert Bibliography. You can edit the bibliography as needed.
