+# Contributing
+
+## Welcome! 👋
+
+Hello there, contributor! We're delighted that you're considering contributing to the `era-test-node` project. This document is here to guide you through the steps and best practices for contributing to this Rust-based repository.
+
+Please take a moment to review this document to ensure a smooth and efficient contribution process for everyone involved.
+
+## Getting Started
+
+- **Fork the repository.** Begin by forking the main `era-test-node` repository to your personal GitHub account.
+
+- **Clone the repository.** After forking, clone the repository to your local machine:
+
+```bash
+git clone https://github.com/<your-github-username>/era-test-node.git
+```
+
+- **Create a new branch.** Use descriptive names for your branches to help identify the feature, bugfix, or enhancement you're addressing:
+
+```bash
+git checkout -b feature/description-of-your-feature
+```
+
+## Making Changes
+
+- **Write your code.** Ensure your code is thoroughly tested and functions as expected. Clear, well-commented code is always appreciated.
+
+- **Compile and test.** Before submitting a pull request, ensure your code compiles, passes lint checks, and all tests are successful. You should also write unit tests for your contributions. Use the following command for these checks:
+
+```bash
+make all
+```
+
+- **Commit your changes.** Adhere to the [Conventional Commits](https://www.conventionalcommits.org/) standard when writing commit messages.
+
+- **Push your changes.** Push the changes to your forked repository:
+
+```bash
+git push origin feature/description-of-your-feature
+```
+
+## Submitting a Pull Request
+
+- **Initiate a pull request (PR).** Go to the main `era-test-node` repository. Your recently pushed branch should be highlighted, showing a "Compare & pull request" button. Click on it and provide a clear, detailed description of your changes in the PR.
+
+- **Await a review.** Our maintainers will review your PR. They might request changes or clarifications, so be ready to address any feedback.
+
+## Code Style Guide
+
+We follow Rust's official coding style guidelines. Before committing, ensure your code is formatted and lint checks pass:
+
+```bash
+cargo fmt --all -- --check &&
+cargo clippy -Zunstable-options -- -D warnings --allow clippy::unwrap_used
+```
+
+This ensures consistent code style throughout the project and helps identify potential issues early.
+
+## Need Assistance?
+
+If you're unsure about something or have questions, don't hesitate to open an issue or initiate a discussion in our [zkSync Community Hub](https://github.com/zkSync-Community-Hub/zkync-developers/discussions). We're here to assist!
+
+## What's Next?
+
+Once your PR is approved and merged, your contribution will be integrated into the `era-test-node` repository. Congratulations, and thank you! We value your contribution and look forward to future collaborations.
+
+Remember, the best contributions come from enjoying the process, being respectful, and continuously learning. Thanks for being a part of our community!
