+        ]
    }
    ```
    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!

-### Notes & Gotchas
- 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.
+### Gotchas
 - 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`.
