# 6.1. Available Packages

This is the list of packages included in LAMMPS. The link for each package name gives more details.

Packages are supported by either the LAMMPS developers or the contributing authors and written in a syntax and style consistent with the rest of LAMMPS.

The “Examples” column is a subdirectory in the examples directory of the distribution which has one or more input scripts that use the package. E.g. `peptide` refers to the `examples/peptide` directory; `PACKAGES/atc` refers to the `examples/PACKAGES/atc` directory. The “Lib” column indicates`` whether an extra library is needed to build and use the package:

- no = no library

- sys = system library: you likely have it on your machine

- int = internal library: provided with LAMMPS, but you may need to build it

- ext = external library: you will need to download and install it on your machine
