At this point, Zotero should be ready to generate a bibliographic file (e.g., .bib file) for use with your LaTeX document. To do this, go back to the main Zotero page and navigate to File > Export Library. Make sure Format is set to 'Better BibLaTeX' and select the option to 'Keep updated'. This will ensure that any changes you make to your parent Zotero library will be pushed out to the exported .bib file.
