  The oxDNA model of DNA has been applied widely to systems in biology,
biophysics and nanotechnology. It is currently available via two independent
open source packages. Here we present a set of clearly-documented exemplar
simulations that simultaneously provide both an introduction to simulating the
model, and a review of the model's fundamental properties. We outline how
simulation results can be interpreted in terms of -- and feed into our
understanding of -- less detailed models that operate at larger length scales,
and provide guidance on whether simulating a system with oxDNA is worthwhile.
