I'd start with the last paragraph of the help information:
"Alternatively, the molecules can be inserted only at positions defined in
positions.dat (-ip). That file should have 3 columns (x,y,z), that give the
displacements compared to the input molecule position (-ci). Hence, if that
file should contain the absolute positions, the molecule must be centered on
(0,0,0) before using gmx insert-molecules (e.g. from gmx editconf -center).
Comments in that file starting with # are ignored."
