  The purpose of this article is to provide a starter kit for multicanonical
simulations in statistical physics. Fortran code for the $q$-state Potts model
in $d=2, 3,...$ dimensions can be downloaded from the Web and this paper
describes simulation results, which are in all details reproducible by running
prepared programs. To allow for comparison with exact results, the internal
energy, the specific heat, the free energy and the entropy are calculated for
the $d=2$ Ising ($q=2$) and the $q=10$ Potts model. % in a temperature range
from $T=\infty$ down to sufficiently low % temperatures, such that the
groundstates are included in the sampling. Analysis programs, relying on an
all-log jackknife technique, which is suitable for handling sums of very large
numbers, are introduced to calculate our final estimators.
