 4. Build gpu-miner:
    1. Clone gpu-miner to local
 
-   ``` sh
+   ``` shell
    git clone https://github.com/alephium/gpu-miner.git
    ```
    2. Open a powershell window, and launch the build script:
 
-   ```sh
+   ```shell
    cd your-gpu-miner-dir
    .\build.ps1

+   Executable file will be generated in `your-gpu-miner-dir/bin/` directory.
