 ## Requirements
-AGILE should run on most modern web browsers. It does, however, rely on some browser APIs that are relatively recent, such as the SharedArrayBuffer and Origin Private File System. It has been tested on Chrome, Edge, Firefox and Safari, both the desktop and mobile versions, and has been confirmed to work. If it doesn't work for you, then check to make sure that you have updated your browser to the latest version. If it still doesn't work, please create an issue under the [Issues](https://github.com/lanceewing/agile-gdx/issues) section above with the details of your device and browser version.
