 # Euromix model to SBML
 
-This repository contains a re-implementation of the EuroMix PBK model[^1] in [Antimony](https://tellurium.readthedocs.io/en/latest/antimony.html) and demonstrates how this Antimony model implementation is automatically converted to an annotated Systems Biology Markup Language ([SBML](https://sbml.org/)) file using the [SBML PBK workflow](https://github.com/jwkruisselbrink/sbml-pbk-workflow). The purpose of this repository is to test/demonstrate how to create and publish interoperable PBK models using the EuroMix PBK model as example.
