 ##### Force fields released by the Open Force Field Initiative can be accessed in the GitHub [repository](https://github.com/openforcefield/openforcefields).
 
-The files available for [download](https://github.com/openforcefield/openforcefields/releases) are in SMIRKS Native Open Force Field (SMIRNOFF) format. Details about this new format are documented in our recent [publication](https://www.doi.org/10.1021/acs.jctc.8b00640) (or [preprint](https://doi.org/10.1101/286542)), and the most recent specification can be found in the [Open Force Field Toolkit documentation](https://open-forcefield-toolkit.readthedocs.io/en/latest/smirnoff.html). You can parameterize small molecules with SMIRNOFF using the ForceField class in the [Open Force Field toolkit](https://github.com/openforcefield/openforcefield) for simulations with [OpenMM](http://openmm.org/). The resulting system can also be converted to several other simulation formats using [ParmEd](http://parmed.github.io/ParmEd/html/index.html). Usage examples can be found in our [GitHub repository](https://github.com/openforcefield/openff-toolkit/tree/master/examples).

-Sage (OpenFF 2.y.z) is the codename for the second generation of the small molecule force fields released by the Open Force Field Initiative. This line of force field release contains our first set of retrained Lennard-Jones parameters in addition to continued improvements to the valence parameters. All scripts, inputs and the results generated as part of the training the Sage line of OpenFF force fields can be found in [openff-sage](https://github.com/openforcefield/openff-sage) Github repository.
