We describe the hybridization-expansion continuous-time quantum Monte Carlo
code package "w2dynamics", developed in Wien and W\"urzburg. We discuss the
main features of this multi-orbital quantum impurity solver for the Anderson
impurity model, dynamical mean field theory as well as its coupling to density
The w2dynamics package allows for calculating one- and
two-particle quantities; it includes worm and further novel sampling schemes. Details about its download, installation, functioning and the relevant
parameters are provided.
