Check if git is installed on this system. If git is not installed, install it using the appropriate package manager for the current OS (e.g. apt, brew, choco). Verify git is available before continuing — if it cannot be installed, stop and report the error.

Clone the repository https://github.com/mosayic-io/mobile-app-starter.git into the current directory. After cloning, verify the directory exists and contains a package.json. If the clone fails for any reason (network error, repo not found, auth failure), stop immediately and report the error. Do NOT attempt to scaffold, generate, or invent a replacement codebase — the project must come from this repository.

Once the repo is cloned and verified, install all dependencies by running `npm install` inside the project directory. If dependency installation fails, report the error and stop.

After successful installation, print a clearly formatted summary explaining:

1. The project has been set up and is ready to run.
2. To start the development server, run: `npx expo start`
3. To preview the app on a physical device, download the "Expo Go" app from the App Store (iOS) or Google Play Store (Android).
4. Once Expo Go is installed, scan the QR code shown in the terminal after running `npx expo start` to open the app on your device.
