Firebase

You will need a firebase project, add one from here : https://console.firebase.google.com/

Once a project is created, do the following. 1. Click on Project overview from the sidebar. 2. Open Service accounts tab. 3. You will see the option to generate a new private key in the firebase admin sdk sub-section. Click on that. 4. Read the warning, and then generate the key. Rename the downloaded key to - firebase_service_account.json and move it to server folder in the root of momentum source code. \

Note: The file name 'firebase_service_account.json' is already part of .gitignore and should be safe to use. It never goes on git. But in case you loose it, you'll need a new one. So keep it secure and safe. (Repeating the warning that google gave you during key generation)
