-  An API standard for single-agent reinforcement learning
-  environments, with popular reference environments and
-  related utilities (formerly Gym)
+  Gymnasium is an open-source library providing an API for
+  reinforcement learning environments. Its main contribution
+  is a central abstraction for wide interoperability between
+  benchmark environments and training algorithms. Gymnasium
+  comes with various built-in environments and utilities to
+  simplify researchers’ work along with being supported by
+  most training libraries. This paper outlines the main
+  design decisions for Gymnasium, its key features, and the
+  differences to alternative APIs.

 * [CleanRL](https://github.com/vwxyzjn/cleanrl) is a learning library based on the Gymnasium API. It is designed to cater to newer people in the field and provides very good reference implementations.
 * [PettingZoo](https://github.com/Farama-Foundation/PettingZoo) is a multi-agent version of Gymnasium with a number of implemented environments, i.e. multi-agent Atari environments.
 * The Farama Foundation also has a collection of many other [environments](https://farama.org/projects) that are maintained by the same team as Gymnasium and use the Gymnasium API.
-* [Comet](https://www.comet.com/site/?utm_source=gymnasium&utm_medium=partner&utm_campaign=partner_gymnasium_2023&utm_content=github) is a free ML-Ops tool that tracks rewards, metrics, hyperparameters, and code for ML training runs. Comet has an easy-to use integration with Gymnasium, here's a [tutorial](https://bit.ly/CometGymnasiumIntegration) on how to use them together! Comet is a sponsor of the Farama Foundation!

 ## Environment Versioning
 
-Gymnasium keeps strict versioning for reproducibility reasons. All environments end in a suffix like "-v0".  When changes are made to environments that might impact learning results, the number is increased by one to prevent potential confusion. These inherit from Gym.
