+After the above installation, you can optionally do some configuration in Visual Studio Code to easily format cmake files.
+1. Install `cmake-format` extension in Visual Studio Code.
+2. Configure the extension. To do this, open the settings (File -> Preferences -> Settings), search for `cmake-format`,
+   and do the below settings:
+   * Set Args: `--first-comment-is-literal=True`.
+   * Set Exe Path to the path of the `cmake-format` command. If you installed `cmake-format` in a standard
+      location, you might not need to change this setting.
+3. Now, you can format your CMake files by right-clicking in a file and selecting `Format Document`.
