+## How to monitor TOR (.onion) services?
+
+To monitor TOR hidden services (.onion URLs) you can use the built-in TOR support of StartOS. 
+
+Follow these steps to create a new proxy in Uptime Kuma:
+
+- Log in to Uptime Kuma
+- Go to 'Settings' (top right menu)
+- Go to 'Proxies' and click 'Setup Proxy'
+- Use the following settings:
+  - Proxy Protocol: `SOCKS v5 (+ DNS)`
+  - Server Address: `embassy`
+  - Port: `9050`
+  - Enabled: `on`
+
+When adding or editing monitors, you can now select this new proxy: `embassy:9050 (socks5h)`
+
+You only have to create this proxy once and can then use it for all your '.onion' HTTP(s) monitors.
+
+Happy monitoring!
