This extension aims to make Zotero (and soon Juris-M) effective for us text-based authoring holdouts; currently, that translates to the LaTeX/Markdown crowd. To get started, read the Installation instructions. At its core, it behaves like any Zotero import/export module; anywhere you can export or import bibliography items in Zotero, you'll find Better Bib(La)TeX listed as one of the choices. If nothing else, you could keep your existing workflow as-is, and just enjoy the improved LaTeX ↔ unicode translation on import and export and more accurate field mapping. Zotero does all its work in UTF-8 Unicode, which is absolutely the right thing to do. Unfortunately, for those shackled to BibTeX and who cannot (yet) move to BibLaTeX, unicode is a major PITA. Also, Zotero supports some simple HTML markup in your references that Bib(La)TeX won't understand.
