3. Make sure you have already installed Node  (NPM) on your local machine. You can download it from [here](https://nodejs.org/en/download).
4. **Dependencies**: Review the repository's documentation or README file for any specific dependencies required by the library.

#### Environment Setup

   ```
2. **Navigate to the Directory**: Move into the directory of the cloned repository:<br>

   ```bash
   cd xchain-lib
   ```

**Note:** Some repositories might require building before use. Follow the instructions in the repository's [README ](https://github.com/xchainjs/xchainjs-lib/blob/master/README.md)or [documentation ](https://github.com/xchainjs/xchainjs-lib/tree/master)for how to build the library, if necessary.
