# Building


You can build source code with hb or the **build.sh** script. This section exemplifies how to build source code with hb. For details about how to build with the **build.sh** script, see [Building Source Code Using the build.sh Script](../quick-start/quickstart-lite-reference.md).


Go to the root directory of the source code in the Ubuntu environment and perform the following steps:


1. Set the build path.
     
   ```
   hb set
   ```

2. Select the current path.
     
   ```
   .
   ```

3. Select **wifiiot_hispark_pegasus** under **hisilicon** and press **Enter**.

4. Start building.
