  AMFlow is a Mathematica package to numerically compute dimensionally
regularized Feynman integrals via the recently proposed auxiliary mass flow
method. In this framework, integrals are treated as functions of an auxiliary
mass parameter and their results can be obtained by constructing and solving
differential systems with respect to this parameter, in an automatic way. The
usage of this package is described in detail through an explicit example of
double-box family involved in two-loop $t\bar{t}$ hadroproduction.
