It serves as a template or blueprint. It contains the keys (names) of the environment variables but (secrets) themselves. Key Characteristics
For services like Stripe or AWS, use official testing prefixes (e.g., pk_test_... ) to signal to developers that they should use sandbox accounts, preventing accidental production interactions during local testing. Advanced Automation: Keeping Files in Sync
