+## Introduction
+🚀TensorNEAT, a part of EvoX project, aims to enhance the NEAT (NeuroEvolution of Augmenting Topologies) algorithm by incorporating GPU acceleration. Utilizing JAX for parallel computations, it extends NEAT's capabilities to modern computational environments, making advanced neuroevolution accessible and fast.
 
 ## Requirements
-* available [JAX](https://github.com/google/jax#installation) environment;
+TensorNEAT requires:
-* [gymnax](https://github.com/RobertTLange/gymnax) (optional).
+- jax (version >= 0.4.16)
-
+- jaxlib (version >= 0.3.0)
+- brax [optional]
+- gymnax [optional]
