+### Emulating the Desktop app instead of the web
+
+1. Baileys, by default, emulates a chrome web session
+2. If you'd like to emulate a desktop connection (and receive more message history), add this to your Socket config:
+    ``` ts
+    const conn = makeWASocket({
+        ...otherOpts,
+        // can use Windows, Ubuntu here too
+        browser: Browsers.macOS('Desktop'),
+        syncFullHistory: true
+    })
+    ```
+
 ## Saving & Restoring Sessions
 
 You obviously don't want to keep scanning the QR code every time you want to connect.
