# Environment Variables

Sensitive information like API keys and tokens are stored inside the `.env` file.

When deploying your application, you should ensure these values are set up in your production  environment and ignore the .env file included with Gravity, as this is for development purposes only. 

Below is a list of the variables used in Gravity. Required variables will be populated for you during the setup process.
