Here, we present the survey strategy, data processing, catalogue construction, and database schema. The first data release dataset includes over 66000 images from the Shallow Survey component, covering an area of 17200 deg^2^ in all six SkyMapper passbands uvgriz, while the full area covered by any passband exceeds 20000 deg^2^. The catalogues contain over 285 million unique astrophysical objects, complete to roughly 18mag in all bands. We compare our griz point-source photometry with Pan-STARRS1 first data release and note an RMS scatter of 2%. The internal reproducibility of SkyMapper photometry is on the order of 1%. Astrometric precision is better than 0.2arcsec based on comparison with Gaia first data release. We describe the end-user database, through which data are presented to the world community, and provide some illustrative science queries. Description: SkyMapper is a purpose-built, optical wide-field survey facility located at Siding Spring Observatory near Coonabarabran in New South Wales, Australia, at the edge of the Warrumbungle National Park, which is Australia's first declared Dark Sky Park. It has a 1.35m primary mirror and uses a mosaic of 32 CCDs, each having 2048x4096-pixels with a scale of  0.5". The 268 million pixels cover a nearly-square field-of view measuring 2.4x2.3deg^2^. After the commissioning phase ended in March 2014, observations for the Southern Survey started. The telescope is fully robotic and nightly survey operations are planned by autonomous scheduler software that can execute the entire survey without needing human intervention.
