 # Enhanced Monte Carlo (EMC) Python Interface
-
-This Python module is a thin layer around the [EMC](http://montecarlo.sourceforge.net/emc/Welcome.html) package that allows you to use EMC with ease.
-
-The package should work out of the box without any configuration as the pre-compiled EMC executable files are included. Please open an issue if you find something missing or not working as expected.

+This module is a thin Python wrapper library of the [EMC](http://montecarlo.sourceforge.net/emc/Welcome.html) package that allows you to use all EMC functionalities with Python interface. 
+
+- See the [example input files](https://github.com/kevinshen56714/emc-pypi/tree/main/pyemc/emc/examples/setup) on how to prepare EMC input (.esh) files.
+- See the [docs](https://github.com/kevinshen56714/emc-pypi/blob/main/pyemc/emc/docs/emc.pdf) to understand more about EMC.

 ## Installation
 
 ```bash
 pip install emc-pypi

+## About [EMC](http://montecarlo.sourceforge.net/)
+EMC creates input structures from SMILES strings and LAMMPS input files for particle simulations. Supported force fields are
+- Atomistic: Born, COMPASS, PCFF, CHARMM, OPLS, TraPPE
+- Coarse-grained: DPD, Martini, SDK
