+## SSH Setup (Required)
+
+Update Manager uses SSH to connect to your hosts.
+
+You must have SSH key-based authentication set up (no password prompts).
+
+### Generate SSH key (if not already done)
+
+```bash
+ssh-keygen -t ed25519
+```
+
+---
+
+### Copy key to hosts
+
+```bash
+ssh-copy-id user@192.168.1.10
+ssh-copy-id user@192.168.1.20
+ssh-copy-id user@192.168.1.30
+```
+
+---
+
+### Test connection
+
+```bash
+ssh user@192.168.1.10
+```
+
+You should be able to connect **without entering a password**.
+
+> ⚠️ If SSH is not configured, the tool will fail or hang during execution.
