Steps

1. Download the cli.sh and move it into a scripts/ directory and execute chmod 755 scripts/cli.sh, this will make the script executable.
2. Export your iOS Distribution private key from your Keychain into the scripts/ folder and name it ios_distribution.p12 make sure to note down the password as we will need it later. It is highly recommended to give it a very strong password.
3. Download your Distribution provisioning profile from the Member Center
4. Rename the provisioning profile to Release.mobilprovision
5. At the top of the script you may need to adjust a few values:

SCHEME="" # Your scheme
