Status and Commissioning of the CMS Experiment

After a brief overview of the Compact Muon Solenoid (CMS) experiment, the status of construction and installation is described. The second part of the document is devoted to a discussion of the general commissioning strategy of the CMS experiment, with a particular emphasis on trigger, calibration and alignment. Aspects of b-physics, as well as examples for early physics with CMS, are also presented. CMS will be ready for data taking in time for the first collisions in the Large Hadron Collider (LHC) at CERN in late 2007.
