We present the version 2.0 of the program pack-ageGoSamfor the automated calculation of one-loop ampli-tudes.GoSamis devised to compute one-loop QCD and/orelectroweak corrections to multi-particle processes withinand beyond the Standard Model. The new code containsimprovements in the generation and in the reduction of theamplitudes, performs better in computing time and numer-ical accuracy, and has an extended range of applicability.The extended version of the “Binoth-Les-Houches-Accord”interface to Monte Carlo programs is also implemented. Wegive a detailed description of installation and usage of thecode, and illustrate the new features in dedicated examples.
