+## Contributing code
+
+### Getting Started
+
+All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose. Consult GitHub Help for more information on using pull requests.
+Before raising a pull request, ensure you have raised a corresponding issue and discussed a possible solution with a maintainer. This gives your pull request the highest chance of getting merged quickly.
+
+### Good First Issues 
+
+Looking for issues to contribute? Check out the [GitHub Issue](https://github.com/csgoh/processpiper/issues) page.
+
+### 🍴 Git Workflow
+
+We use [Github Flow](https://guides.github.com/introduction/flow/index.html), so all code changes happen through pull requests. 
+
+1. Fork the repo and create a new branch from the `main` branch.
+2. Branches are named as `fix/fix-name` or `feature/feature-name`
+3. Please add tests for your changes. 
+4. Once you are confident in your code changes, create a pull request in your fork to the release branch in the appsmithorg/appsmith base repository.
+5. If you've changed any functions, please call this out in the pull request and ensure backward compatibility.
+6. Link the issue of the base repository in your Pull request description. [Guide](https://docs.github.com/en/free-pro-team@latest/github/managing-your-work-on-github/linking-a-pull-request-to-an-issue)
+7. When you raise a pull request, we automatically run tests on our CI. Please ensure that all the tests are passing for your code change. We will not be able to accept your change if the test suite doesn't pass.
