In light of the conspicuous absence of SUSY in the energy range explored by the LHC during run I, non-supersymmetric BSM scenarios are becoming more and more attractive. One key ingredient in exploring such BSM physics are the renormalization group equations (RGEs) that are essential for extrapolating the theory to higher energy scales. Although the two-loop RGEs for a general quantum field theory have been known for some time, it is only recently that their automation has become available in the form of a Python program called PyR@TE. In this talk, I will present the features of PyR@TE as well as the latest developments of the code. In particular, the new ability to deal with sets of fields that have multiple ways of being contracted into a gauge singlet.<br/>Presentation at the DPF 2015 Meeting of the American Physical Society Division of Particles and Fields, Ann Arbor, Michigan, August 4-8, 2015<br/>
