Overview
--------

``FastSpecFit`` is a stellar continuum and emission-line modeling code which is
optimized for speed and simplicity; it uses physically motivated stellar
population synthesis and emission-line templates to jointly model UV/optical
spectrophotometry and ultraviolet through infrared broadband photometry
(``fastspec``). Alternatively, it can be used to model just the broadband
photometry (``fastphot``).

``FastSpecFit`` currently only supports `DESI <https://desi.lbl.gov>`_
spectrophotometric data, although contributions to develop the software for
other instruments and surveys are more than welcome.
