+### Do I need a Mac mini for iMessage support?
+
+You need **some macOS device** signed into Messages. It does **not** have to be a Mac mini —
+any Mac works. Clawdbot’s iMessage integrations run on macOS (BlueBubbles or `imsg`), while
+the Gateway can run elsewhere.
+
+Common setups:
+- Run the Gateway on Linux/VPS, and point `channels.imessage.cliPath` at an SSH wrapper that
+  runs `imsg` on the Mac.
+- Run everything on the Mac if you want the simplest single‑machine setup.

 ### Can I use Bun?
 
 Bun is **not recommended**. We see runtime bugs, especially with WhatsApp and Telegram.
