+title: Cosmovisor (Optional)
+---
+
+[Cosmovisor](https://docs.cosmos.network/v0.52/build/tooling/cosmovisor) is a comprehensive process manager that can serve as an easy substitute for the standard `initiad start` command. It is designed for both manual use and as a system service, offering automatic updates for blockchains based on the Cosmos SDK. Cosmovisor's main role is to keep track of software upgrade proposal signals and automatically download and update the node to the new binary following proposal approval.
+
+<Steps>
+	<Step title="Install Cosmovisor">
+		```sh
+		go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@latest
+
+		export DAEMON_HOME=~/.initia
+		export DAEMON_NAME=initiad
+
+		cosmovisor init ~/go/bin/initiad # <path-to-executable>
+
+		# only if there is planned upgrade
+		export UPGRADE_NAME=<upgrade-name>
+		export UPGRADE_VERSION=<upgrade-version>
+		mkdir -p $DAEMON_HOME/cosmovisor/upgrades/$UPGRADE_NAME/bin
+		(                                                                              \
+			cd initia &&                                                           \
+			git fetch --all --tags &&                                              \
+			git checkout $UPGRADE_VERSION &&                                       \
+			make build &&                                                          \
+			mv ./build/initiad $DAEMON_HOME/cosmovisor/upgrades/$UPGRADE_NAME/bin/ \
+		)
+		```
+	</Step>
+	<Step title="Update System Service File">
+		```sh
+		[Unit]
+		Description=initiad
+
+		[Service]
+		Type=simple
+		User=ubuntu
+		ExecStart=/home/ubuntu/go/bin/cosmovisor run start --home /home/ubuntu/.initia
+		WorkingDirectory=/home/ubuntu/.initia
+		Restart=on-abort
+		StandardOutput=syslog
+		StandardError=syslog
+		SyslogIdentifier=initiad
+		LimitNOFILE=4096
+		Environment="DAEMON_NAME=initiad"
+		Environment="DAEMON_HOME=/home/ubuntu/.initia" 
+		Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
+		Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
+		Environment="DAEMON_RESTART_DELAY=5s"
+		Environment="UNSAFE_SKIP_BACKUP=true"
+
+		[Install]
+		WantedBy=multi-user.target
+		```
+
+		<Note> 
+		To update the node manually, set the environment variable `DAEMON_ALLOW_DOWNLOAD_BINARIES=false`. This disables automatic binary downloads. Afterward, download the required binary yourself and place it in the designated installation directory. 
+		</Note>
+	</Step>
+	<Step title="Restart initiad">
+		```sh
+		sudo systemctl daemon-reload
+		sudo systemctl restart initiad
+		```
+	</Step>
+</Steps>
