+### How to Build Your Own Application
+
+NanoKVM Desk will search for all folders in the system's `/userapp` directory and use the folder names as APP names. It is recommended to keep folder names under 8 characters.
+
+In the `User APP` interface, when you click on a user-defined application, the system will attempt to launch a Python application named `main.py` inside the corresponding folder.
+
+At this point, the small screen uses the standard FB driver, allowing users to utilize `/dev/fb0` to implement custom screen display operations.
