Launched on 13 July 2019 from Baikonur, in the next years the German eROSITA instrument on the
Russian Spectrum-X-Gamma satellite will perform a deep all sky survey in the 0.2-10keV band,
which will be significantly deeper than existing surveys in that band. I will give an overview of
the eROSITA instrument, present the survey design, and present first results from the performance
verification phase as well as the initial survey phase.
