-
-# Or manually:
-`cd /opt/docker/dashboard && ./update-dash.sh`
+Quick commands for common homelab tasks. For detailed procedures, see the [Operations](./operations/) directory.
 
 ## 🐳 Docker Maintenance

-## ☁️ Backup & Cloud Storage
-Manual triggers and verification for your S3 backups.
-
-# Run a manual backup immediately
-`/opt/docker/backups/backup-homelab.sh`
-
-# List files in your Linode Object Storage bucket
-`rclone ls linode-s3:davisdre-backups-chicago`
-
-# Check the backup log for errors
-`tail -n 20 /opt/docker/backups/backup.log`
-
-## 🖥️ System Health & Monitoring
-Keep an eye on that 2GB RAM limit and swap space.
-
-# The 'Gold Standard' for real-time monitoring
-`htop`
-
-# Check disk space usage
-`df -h`
-
-# Check swap utilization specifically
-`swapon --show`
-
-## 🛠️ Infrastructure SOP: Adding a New App
-1. Update global-db/compose.yaml environment list.
-2. Manually provision the DB on the live instance:
+## 🐘 Database Operations
 ```bash
-docker exec -it global_postgres psql -U postgres -c "CREATE DATABASE app_name;"
-docker exec -it global_postgres psql -U postgres -c "CREATE USER app_name WITH PASSWORD 'my-custom-password';"
-docker exec -it global_postgres psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE app_name TO app_name;"
-docker exec -it global_postgres psql -U postgres -c "ALTER DATABASE app_name OWNER TO app_name;"
-```
+# Access Postgres CLI
+docker exec -it global_postgres psql -U postgres
+```
+*SQL inside psql:* `\l` (list DBs), `\du` (list users).
+
+## ☁️ Backup & Cloud Storage
+```bash
+# Manual backup trigger
+/opt/docker/backups/backup-homelab.sh
+
+# List remote backups
+rclone ls linode-s3:davisdre-backups-chicago
+
+# View logs
+tail -n 20 /opt/docker/backups/backup.log
+```
+
+## 🖥️ System Health
+```bash
+# Real-time monitoring
+htop
+
+# Disk usage
+df -h
+
+# Swap space
+swapon --show
+```
