+# Hardhat Template for ZetaChain
+
+This is a simple Hardhat template that provides a starting point for developing
+smart contract applications on ZetaChain.
+
+## Prerequisites
+
+Before getting started, ensure that you have
+[Node.js](https://nodejs.org/en/download) (version 18 or above) and
+[Yarn](https://yarnpkg.com/) installed on your system.
+
+## Getting Started
+
+To get started, install the necessary dependencies:
+
+```
+yarn
+```
+
+## Hardhat Tasks
+
+This template includes Hardhat tasks that streamline smart contract development.
+Learn more about the template and the functionality it provides
+[in the docs](https://www.zetachain.com/docs/developers/template/).
+
+## Next Steps
+
+To learn more about building decentralized apps on ZetaChain, follow the
+tutorials available in
+[the introduction to ZetaChain](https://www.zetachain.com/docs/developers/overview/).
