  In completely generic four-dimensional gauge-Yukawa theories, the
renormalization group $ \beta $-functions are known to the 3-2-2 loop order in
gauge, Yukawa, and quartic couplings, respectively. It does, however, remain
difficult to apply these results to specific models without the use of
dedicated computer tools. We describe a procedure for extracting $ \beta
$-functions using the general results and introduce RGBeta, a dedicated
Mathematica package for extracting the $ \overline{\text{MS}} $ $ \beta
$-functions in broad classes of models. The package and example notebooks are
available from the GitHub repository at https://github.com/aethomsen/RGBeta .
