+# Contributing Guidelines
+
+Thank you for your interest in contributing to our project. Whether it's a bug report, new feature, correction, or additional
+documentation, we greatly value feedback and contributions from our community.
+
+Please read through this document before submitting any issues or pull requests to ensure we have all the necessary
+information to effectively respond to your bug report or contribution.
+
+
+## Reporting Bugs/Feature Requests
+
+We welcome you to use the GitHub issue tracker to report bugs or suggest features.
+
+When filing an issue, please check [existing open](https://github.com/FreeRTOS/backoffAlgorithm/issues), or [recently closed](https://github.com/FreeRTOS/backoffAlgorithm/issues?q=is%3Aissue+is%3Aclosed), issues to make sure somebody else hasn't already
+reported the issue. Please try to include as much information as you can. Details like these are incredibly useful:
+
+* A reproducible test case or series of steps
+* The version of our code being used
+* Any modifications you've made relevant to the bug
+* Anything unusual about your environment or deployment
+
+
+## Contributing via Pull Requests
+Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:
+
+1. You are working against the latest source on the *main* branch.
+1. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
+1. You open an issue to discuss any significant work - we would hate for your time to be wasted.
+
+To send us a pull request, please:
+
+1. Fork the repository.
+1. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
+1. Ensure that your contributions conform to the [style guide](https://docs.aws.amazon.com/embedded-csdk/202011.00/lib-ref/docs/doxygen/output/html/guide_developer_styleguide.html).
+1. Format your code with uncrustify, using the config available in [FreeRTOS/CI-CD-Github-Actions](https://github.com/FreeRTOS/CI-CD-Github-Actions/blob/main/formatting/uncrustify.cfg).
+1. Ensure local tests pass.
+1. Commit to your fork using clear commit messages.
+1. Send us a pull request, answering any default questions in the pull request interface.
+1. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.
+
+GitHub provides additional document on [forking a repository](https://help.github.com/articles/fork-a-repo/) and
+[creating a pull request](https://help.github.com/articles/creating-a-pull-request/).
+
+
+## Finding contributions to work on
+Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels ((enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any ['help wanted'](https://github.com/FreeRTOS/backoffAlgorithm/labels?q=help+wanted) issues is a great place to start.
+
+
+## Code of Conduct
+This project has adopted the [Amazon Open Source Code of Conduct](https://aws.github.io/code-of-conduct).
+For more information see the [Code of Conduct FAQ](https://aws.github.io/code-of-conduct-faq) or contact
+[email protected] with any additional questions or comments.
+
+
+## Security issue notifications
+If you discover a potential security issue in this project we ask that you notify AWS/Amazon Security via our [vulnerability reporting page](https://aws.amazon.com/security/vulnerability-reporting/). Please do **not** create a public github issue.
+
+
+## Licensing
+
+See the [LICENSE](../LICENSE) file for our project's licensing. We will ask you to confirm the licensing of your contribution.
+
+We may ask you to sign a [Contributor License Agreement (CLA)](https://en.wikipedia.org/wiki/Contributor_License_Agreement) for larger changes.
