     This will allow VSCode to automatically launch VirtualBox once Asuro has been compiled.
+    
+    You can also enable the serial adapter "COM1" in mode "Raw File", give it a path, and provide this path in the `localenv.json` as follows:
+    ```json
+    {
+        "VirtualBox" : {
+            "MachineName": "<YOUR_UUID_OR_MACHINE_NAME>",
+            "LogLocation": "Fully\\Qualified\\Path\\To\\Your\\Log\\File"
+        }
+    }
+    ```
+    This will allow you to see the console output from Asuro in your host terminal.
 13. Open your project folder in VSCode, use CTRL+SHIFT+B to build & F5 to build + run in VBox.
 14. Congratulations! You can now play with Asuro!

-- It was noted that Windows builds above `20H2` seem to have issues installing WSL2. We may have to wait for a patch from Microsoft to fix this. Our devs are currently using build `20H2`.
+- The above process has been updated to be compatible with VirtualBox 7+, in which VBoxSDL was removed and vboxmanage should be used in its place. A small wrapper powershell script is used to achieve this.
