The European XFEL is a major X-ray Free Electron Laser facility located in Germany between the states of Hamburg and Schleswig-Holstein. It is currently under commissioning and it aims at providing short pulses of radiation with unprecedented brightness covering the photon energy range between below the carbon K-edge and about 25 keV in SASE mode at the fundamental harmonic. It is driven by a superconducting linac working in burst, high-repetition mode, with a nominal energy up to 17.5 GeV, which feeds three separate undulator lines: SASE1 and SASE2, optimized for harder X-rays, and SASE3, optimized for soft X-ray radiation. In this contribution I will first address the present status of the European XFEL, mainly from the machine viewpoint, and I will then move to shortly discussing the status of the future Hard X-ray Self-Seeding setup, which will be installed at SASE2 and promises nearly Fourier-limited pulses of radiation with increased brightness.
