Overview
--------

``FastSpecFit`` is a stellar continuum and emission-line modeling code for `DESI
<https://desi.lbl.gov>`_ which is optimized for speed and simplicity; it uses
physically motivated stellar population synthesis and emission-line templates to
jointly model the three-camera optical spectrophotometry from DESI and the
ultraviolet through infrared broadband photometry (``fastspec``). Alternatively,
it can be used to model just the broadband photometry (``fastphot``), although
in either case DESI redshifts are required.
