  This document describes the general process of setting up, running, and
analysing disc galaxy simulations using the freely available program Phantom of
RAMSES (PoR). This implements Milgromian Dynamics (MOND) with a patch to the
RAMSES grid-based $N$-body and hydrodynamical code that uses adaptive mesh
refinement. We discuss the procedure of setting up isolated and interacting
disc galaxy initial conditions for PoR, running the simulations, and analysing
the results. This manual also concisely documents all previously developed MOND
simulation codes and the results obtained with them.
