+IMAGE_TAG="latest"
 
 # Service-specific variables
 # (Add any configuration specific to your service)
 ```
 
+**CRITICAL REQUIREMENT**: The `SSH_USER` variable MUST be defined in every service.env file. Dropshell uses this internally for server management. Without it, the template will fail with "SSH_USER variable not defined" error.

 **Important**: This is the file users edit to customize each service instance. Different deployments of the same template will have different `service.env` files.
 
 ### How Environment Variables Work

 4. **Valid environment files**: Both `.env` files must be parseable
+5. **SSH_USER defined**: The `SSH_USER` variable MUST be present in `service.env`
