  We present the stellar value-added catalogue based on the Dark Energy
Spectroscopic Instrument (DESI) Early Data Release. The catalogue contains
radial velocity and stellar parameter measurements for $\simeq$ 400,000 unique
stars observed during commissioning and survey validation by DESI. These
observations were made under conditions similar to the Milky Way Survey (MWS)
currently carried out by DESI but also include multiple specially targeted
fields, such as those containing well-studied dwarf galaxies and stellar
streams. The majority of observed stars have $16<r<20$ with a median
signal-to-noise ratio in the spectra of $\sim$ 20. In the paper, we describe
the structure of the catalogue, give an overview of different target classes
observed, as well as provide recipes for selecting clean stellar samples. We
validate the catalogue using external high-resolution measurements and show
that radial velocities, surface gravities, and iron abundances determined by
DESI are accurate to 1 km/s, $0.3$ dex and $\sim$ 0.15 dex respectively. We
also demonstrate possible uses of the catalogue for chemo-dynamical studies of
the Milky Way stellar halo and Draco dwarf spheroidal. The value-added
catalogue described in this paper is the very first DESI MWS catalogue. The
next DESI data release, expected in less than a year, will add the data from
the first year of DESI survey operations and will contain approximately 4
million stars, along with significant processing improvements.
