    Updates can be downloaded and installed by the app.
 
 1. Open the `dmg` and drag the `GitHub Copilot for Xcode.app` into the `Applications` folder.

 1. On the first opening the application it will warn that it was downloaded from the internet. Click `Open` to proceed.

 1. Two important permissions are required for the application to operate well: `Accessibility` and `Xcode Source Editor Extension`. The first time the application is run these permissions should be requested. You may need to click `Refresh` in the settings if not prompted.

 1. To install updates, click `Check for Updates` from the menu item or in the settings application. After installing a new version, Xcode must be restarted to use the new version correctly. New versions can also be installed from `dmg` files downloaded from the releases page. When installing a new version via `dmg`, the application must be run manually the first time to accept the downloaded from the internet warning.
