The self-annihilation, or decay, of dark matter particles could result in significant contributions to cosmic ray fluxes of various kinds and thereby provide a unique opportunity to detect dark matter by means other than through its gravitational interaction. In this talk, I review the basic principles and current state of indirect searches for dark matter with gamma rays. Special emphasis is put on the importance of the pronounced features that may be encountered in the annihilation spectrum. In this context, I will discuss in some detail the recently discovered indication for a line-like signal in the data of the Fermi large area telescope, which would correspond to annihilating DM particles with a mass of around 150 GeV.
