+## KVS Server Management
+
+If you're also running the KVS server locally, you can use the built-in daemon commands:
+
+```bash
+# Start KVS server as background daemon
+./kvs start config.yaml
+
+# Check server status
+./kvs status
+
+# View server logs
+tail -f ~/.kvs/logs/kvs_config.yaml.log
+
+# Stop server
+./kvs stop config
+
+# Restart server
+./kvs restart config
+```
+
+**Multiple instances:**
+```bash
+# Start a 3-node cluster
+./kvs start node1.yaml
+./kvs start node2.yaml
+./kvs start node3.yaml
+
+# Check all running instances
+./kvs status
+
+# Stop entire cluster
+./kvs stop node1
+./kvs stop node2
+./kvs stop node3
+```
+
+For more details on server management, see the [main KVS documentation](../kvs/README.md#-process-management).
