+### Submitting Code Changes
+
+We accept contributions via Pull Requests (PRs). Before submitting a PR, please follow these steps:
+
+1. **Fork the repository** to your GitHub account.
+2. **Create a new branch** for your changes.
+   - If you're creating a bugfix branch, name it XXX-something, where XXX is the issue number.
+   - If you're working on a new feature, first create an issue to announce your intentions, then name the branch XXX-something, where XXX is the issue number.
+3. **Make your changes** in this branch.
+4. **Test your changes** to ensure that they do not break existing functionality.
+5. **Commit your changes** with a meaningful commit message.
+6. **Push your changes** to your forked repository.
+7. **Create a Pull Request** to the main branch of the original repository.
+
+#### How to Create a Pull Request (PR)
+
+1. Go to the [GitHub repository](https://github.com/instaclustr/fft-compression).
+2. Click on the "Pull Requests" tab.
+3. Press the **"New pull request"** button.
+4. Select the **base repository** and the branch where you want to merge your changes (`main`).
+5. Compare this with the branch containing your changes (your forked repository and branch).
+6. Provide a **descriptive title** and **clear description** of the changes in the PR.
+7. Link any relevant issues by adding `Closes #IssueNumber` to the description.
+8. Submit your pull request.
+
+#### Guidelines for Pull Requests
+
+- Provide a clear description of your changes and the problem they solve.
+- Reference any relevant issues or discussions in your PR description.
+- When you make a PR for small change (such as fixing a typo, grammar fix), please squash your commits so that we can maintain a cleaner git history.
+- Include any necessary documentation updates as part of your PR.
+- Ensure that your code adheres to the project's coding standards (see below).
+- Code review comments might be added to your pull request. Please discuss them, implement the suggested changes, and push additional commits to your feature branch. Make sure to leave a comment after pushing. 
+The new commits will appear in the pull request automatically, but the reviewers won't be notified unless you comment.
+- If your PR is a work-in-progress (WIP), please indicate this in the title by prefixing it with `[WIP]`.
+
+If your pull request isn't accepted right away, don't get discouraged! If there are issues with the implementation, you'll likely receive feedback on what can be improved.
+
+### Coding Standards
+
+To maintain consistency and quality across the codebase, please adhere to the following coding standards:
+
+- Follow the naming conventions and coding style already present in the codebase.
+- Keep functions and methods small and focused.
+- Write descriptive comments where necessary, especially in complex sections of code.
+- Ensure your code is linted and formatted according to the project's style guides.
+
+## Running Tests
+
+All code changes should be covered by tests. To run the test suite, use the following command: `cargo test`
+
+## Documentation
+
+Good documentation is crucial for the usability and maintainability of the project. If you are adding a new feature or modifying existing behavior, ensure that you update the relevant documentation files.
+
+- See `docs/README.md` for more information on building the docs and how docs get released.
+- Ensure that your changes are reflected in the usage instructions or other relevant sections.
+
