The High-Altitude Water Cherenkov Observatory (HAWC) collected more than a year of data in its full configuration. With its large field of view and high uptime it is exposed to two-thirds of the sky every day. From the light distribution in the arrays water-Cherenkov tanks we discriminate between electromagnetic and hadronic showers, which enable us to study the cosmic ray and gamma ray sky separately. In this contribution, we will give an overview of the detector and the reconstruction performance. In addition, the TeV gamma-ray sky as observed by HAWC will be presented and we will discuss its major astrophysical results.
