 ## Development
@@ -117,7 +163,6 @@ Before you begin, ensure you have the following tools installed on your system:
 - **Node.js**: Version 16 or later. [Download Node.js](https://nodejs.org/)
 - **npm**: Comes with Node.js, or install it separately if needed.
 - **Unbound**: Ensure that `unbound-control` is installed and properly configured. Follow the [Unbound installation guide](https://nlnetlabs.nl/documentation/unbound/) for details.
-- **TypeScript**: (Optional) For contributing to or extending the library, TypeScript must be installed globally or as a dev dependency.
