 This is a fork of the AirSim repository, which Microsoft decided to shutdown in July of 2022. This fork serves as a waypoint to building a new and better simulation platform. The creater and maintainer of this fork is Codex Laboratories LLC (our website is [here](https://www.codex-labs-llc.com)). Colosseum is one of the underlying simulation systems that we use in our product, the [SWARM Simulation Platform](https://www.swarmsim.io). This platform exists to provide pre-built tools and low-code/no-code autonomy solutions. Please feel free to check this platform out and reach out if interested.
