Abstract
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique.  The spectra of 35 million galaxies and quasars over 14000 sq deg will be measured during the life of the experiment.  A new prime focus corrector for the KPNO Mayall telescope will deliver light to 5000 fiber optic positioners.  The fibers in turn feed ten broad-band spectrographs. We will describe the extensive preparations of the Mayall telescope and its environs for DESI, and will report on progress-to-date of the installation of DESI itself.
