Modify & extend LAMMPS :h2

LAMMPS is designed in a modular fashion so as to be easy to modify and
extend with new functionality.  In fact, about 95% of its source code
is add-on files.  These doc pages give basic instructions on how to do
this.

If you add a new feature to LAMMPS and think it will be of interest to
general users, we encourage you to submit it for inclusion in LAMMPS
as a pull request on our "GitHub
site"_https://github.com/lammps/lammps, after reading the "Modify
contribute"_Modify_contribute.html doc page.
