     2. Run the Script: Open PowerShell as administrator.
 
-    ```powershell
-    .\setup-flex-bison.ps1
-    ```
+        ```powershell
+        .\setup-flex-bison.ps1
+        ```
 
     3. Restart the command prompt: After the script completes, restart your command prompt or Visual Studio for the changes to take effect.
