 #### 6.1 Generate SSH Key Pair
 
+**Important**: Run this command as the **DEPLOY_USER** (not root or SERVICE_USER). The DEPLOY_USER is responsible for deployment orchestration and SSH communication with the production server.
+
 ```bash
 ssh-keygen -t ed25519 -C "ci-cd-server" -f ~/.ssh/id_ed25519 -N ""
 ```
 
+**What this does**: 
+- Creates an SSH key pair for secure communication between CI/CD and production servers
+- The DEPLOY_USER uses this key to SSH to the production server for deployments
+- The key is stored in the DEPLOY_USER's home directory for security
+
+**Security Note**: The DEPLOY_USER handles deployment orchestration, while the SERVICE_USER runs the actual CI pipeline. This separation provides better security through the principle of least privilege.
