Before you install the application and run it on the development board, install the DevEco Device Tool by following operations provided in  [HUAWEI DevEco Device Tool User Guide](https://device.harmonyos.com/en/docs/ide/user-guides/tool_install-0000001050164976). Burn the HarmonyOS into the development board, and run it on the board. For details about how to compile, burn, and run an image, see the  [Getting Started with Hi3516](../quick-start/introduction-to-the-hi3516-development-board.md). After the image is running normally and the system is started properly, perform the following steps to install or uninstall the application:

1.  Store the compiled unsigned application installation package and installation tool in an SD card and insert the SD card into the development board slot. The installation tool is in  **idev\_tools**  of the directory where the image file is generated.
2.  Run the following command to disable signature verification, which is enabled by default for application installation:

    ```
    ./sdcard/dev_tools/bin/bm set -s disable
    ```

3.  Run the following command to install the application:

    ```
    ./sdcard/dev_tools/bin/bm install -p /sdcard/airquality.hap 
    ```

    The  **dev\_tools**  directory stores the installation tool, and  **airquality.hap**  is the application installation package. Replace it with actual the package name.

4.  After the application is installed, touch the application icon on the home screen to enter the application.
