+# Systemd hosts
+
+These hosts are on the same network as Komodo and have direct access. For simplicity, they run as a [systemd](https://systemd.io/) service.
+
+SSH to the host and run the following command. This command is repeatable and non-destructive and will update to the latest version.
+````bash
+curl -sSL https://raw.githubusercontent.com/moghtech/komodo/main/scripts/setup-periphery.py | python3 - \
+  --core-address="https://komodo.alexlebens.net"
+````
+
+# Docker hosts
+
+These hosts are not on the network and need some kind of VPN connection, such as [Tailscale](https://tailscale.com/). Because of this requirement it becomes simpler to use containers and [Docker networks](https://docs.docker.com/engine/network/).
+
+The hosts should have their [compose](https://docs.docker.com/compose/) files defined in the [infrastructure repository](https://gitea.alexlebens.dev/alexlebens/infrastructure/src/branch/main/hosts). Therefore, [Renovate](https://gitea.alexlebens.dev/alexlebens/infrastructure/actions?workflow=renovate.yaml&actor=0&status=0) will make updates to those files.
+
+<Steps>
+1. SSH to the host and switch user to root.
+    ````bash
+    ssh <hostname>
+    ````
+    
+2. Change directory to where the local git folder is. This can vary per host, but the default should be in the /opt/compose folder.
+    ````bash
+    cd /opt/compose/infrastructure
+    ````
+
+3. Pull the latest changes.
+    ````bash
+    git pull
+    ````
+
+4. Change directory to the host and Komodo app.
+    ````bash
+    cd /opt/compose/infrastructure/hosts/<host>/komodo-periphery
+    ````
+
+5. Bring down the current stack.
+    ````bash
+    docker compose down
+    ````
+
+5. Bring down the stack back up. This should pull the latest image.
+    ````bash
+    docker compose up -d
+    ````
+
+6. Verify updates on the Komodo servers page.
+    ````
+    [https://komodo.alexlebens.net/servers](https://komodo.alexlebens.net/servers)
+    ````
