-**An agent-based, socio-economic-ecological model of agricultural landscapes
-in Europe under the CAP.**
+**A multidisciplinary mechanistic model of agricultural landscapes and ecosystems in Europe.**
 	
 ## Description
 
-Persefone models farmers' decision making and its impact on species in agricultural
-landscapes. The aim is to investigate how policies such as the CAP influence farms and
-biodiversity.
+Persefone.jl models agricultural practice and how it impacts animal species at a landscape
+scale. It includes a farm submodel, a crop growth submodel, and individual-based models
+of multiple indicator species. Its aim is to investigate how changes in farm operations
+(e.g. through policy changes in the CAP) influence biodiversity.
 
 The model is based on the [Agents.jl](https://juliadynamics.github.io/Agents.jl/stable/) 
-framework. It is currently in the very early stages of development.
