+# How to Contribute
+
+Thanks for your interest in contributing to `app-simulator`! Here are a few
+general guidelines on contributing and reporting bugs that we ask you to review.
+Following these guidelines helps to communicate that you respect the time of the
+contributors managing and developing this open source project. In return, they
+should reciprocate that respect in addressing your issue, assessing changes, and
+helping you finalize your pull requests. In that spirit of mutual respect, we
+endeavor to review incoming issues and pull requests within 10 days, and will
+close any lingering issues or pull requests after 60 days of inactivity.
+
+Please note that all of your interactions in the project are subject to our
+[Code of Conduct](/CODE_OF_CONDUCT.md). This includes creation of issues or pull
+requests, commenting on issues or pull requests, and extends to all interactions
+in any real-time space e.g., Slack, Discord, etc.
+
+## Reporting Issues
+
+Before reporting a new issue, please ensure that the issue was not already
+reported or fixed by searching through our [issues
+list](https://github.com/cisco-open/app-simulator/issues).
+
+When creating a new issue, please be sure to include a **title and clear
+description**, as much relevant information as possible, and, if possible, a
+test case.
+
+**If you discover a security bug, please do not report it through GitHub.
+Instead, please see security procedures in [SECURITY.md](/SECURITY.md).**
+
+## Sending Pull Requests
+
+Before sending a new pull request, take a look at existing pull requests and
+issues to see if the proposed change or fix has been discussed in the past, or
+if the change was already implemented but not yet released.
+
+We expect new pull requests to include tests for any affected behavior, and, as
+we follow semantic versioning, we may reserve breaking changes until the next
+major version release.
+
+## Other Ways to Contribute
+
+We welcome anyone that wants to contribute to `app-simulator` to triage and
+reply to open issues to help troubleshoot and fix existing bugs. Here is what
+you can do:
+
+- Help ensure that existing issues follows the recommendations from the
+  _[Reporting Issues](#reporting-issues)_ section, providing feedback to the
+  issue's author on what might be missing.
+- Review existing pull requests, and testing patches against real existing
+  applications that use `app-simulator`.
+- Write a test, or add a missing test case to an existing test.
+
+Thanks again for your interest on contributing to `app-simulator`!
