Molecular Dynamics

Hi,

I am a graduate student. I want to start learning Molecular Dynamics
specially in respest to Continuum Mechanics. Can anybody give me some
light about how to start or which textbook to start with?

 I want to use Large-scale Atomic/Molecular Massively Parallel
Simulator (LAMMPS) package (C++ version). Is there any group/person who is using this package? I need some help.
