 # Crop submodel
 
-Eventually, Persefone will include a full-blown crop-growth model (an adaptation of
-AquaCrop, created by the FAO). At the moment, we are only working with a very basic mock-up.
+Eventually, the plan is to have Persefone include a reimplementation of the AquaCrop model, 
+a well-established crop growth model developed by the FAO. Until then, we are using the
+crop growth submodel used in [ALMaSS](https://doi.org/10.1016/S0304-3800(03)00173-X).

 # Farm submodel
 
-Eventually, Persefone will include multiple farm-decision submodels. At the moment, 
-we are only working with a very basic mock-up.
+Eventually, the aim is to create a full socio-economic farm decision model for Persefone.
+However, for the time being, we will restrict ourselves to a simple model that executes
+typical farm operations and crop rotations.

 # Introduction
 
-Persefone is an agent-based, socio-economic-ecological model of agricultural landscapes
-in Europe under the Common Agricultural Policy (CAP).
+**View the source code on [Gitlab](https://git.idiv.de/xo30xoqa/persefone).**
 
-It's aim is to investigate how policy affects farmer decision-making, and how this in turn
-affects various animal species. It includes a farm submodel, a crop-growth submodel, and
-an ecological submodels.
+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 early stages of development.
