(Molecular dynamics) GROMACS--set up an example calculation

In GROMACS, "gmx dipoles" calculates fluctuations of the total dipole for a simulation system. I would like to run a calculation in GROMACS to check results from another code. However, I don't know how to use GROMACS. I would like someone to set up an ab initio simulation that I can run in GROMACS that uses the module "gmx dipoles" and tell me the basics of how to run it. I would like to run the calculation in the NVT and NPT ensembles. I can provide the input atomic configuration and all other simulation details (like the functional to use, etc).
