While MEmilio already preimplements many different models, it is possible to create new models. This section describes how to create a new model in MEmilio. All of MEmilio's models have been designed to share a maximum of structure and functionality, however, the creation of a new aggregated model differs fundamentally from the creation of a new individual-based model. New metapopulation models are generally created by implementing an aggregated model in a graph structure. In addition, MEmilio also provides an :doc:`extension<sbml>` to create models from Systems Biology Markup Language (SBML) files.
