+## Environment-Level Variables
+
+### Practical Example
+
+Let's consider a scenario where you have:
+- A staging environment with different database credentials
+- Multiple services that need environment-specific configurations
+
+### 1. Define Environment Variable
+
+In the environment's variables section, define:
+
+```bash
+DATABASE_PASSWORD=staging_secret_password
+API_KEY=staging_api_key_12345
+```
+
+### 2. Use the Variable in Services
+
+In each service's environment variables tab, reference the environment variable:
+
+
+```bash
+DATABASE_URL=postgresql://postgres:${{environment.DATABASE_PASSWORD}}@staging-db:5432/postgres
+EXTERNAL_API_KEY=${{environment.API_KEY}}
