 # maxnet
+This is a pure Julia implementation of the [maxnet algorithm](https://github.com/mrmaxent/maxnet).
+
+Maxnet is closely related to the java MaxEnt application, which is widely used in species distribution modelling. It was developped by Steven Philips. Please see [this publication](https://doi.org/10.1111/ecog.03049) for more details about the maxnet algorithm.
