+# Contributor Guide to Upholding the Code of Conduct
+
+Welcome to the AsyncAPI community! As a contributor, you are an essential part of building a safe, inclusive, and respectful environment for everyone. This guide will help you understand how to follow and uphold our [Code of Conduct](https://github.com/asyncapi/community/blob/master/CODE_OF_CONDUCT.md).
+
+
+
+## Why This Matters
+
+The Code of Conduct (CoC) sets expectations for behavior in all AsyncAPI spaces, including repositories, GitHub discussions, communication platforms (such as Slack), and online and physical events. 
+
+Following it helps:
+
+- Foster inclusion and belonging
+- Prevent and resolve conflicts
+- Protect the well-being of all contributors
+
+
+
+## Your Responsibilities as a Contributor
+
+- **Be Respectful:** Treat others with kindness and professionalism.
+- **Be Inclusive:** Welcome diverse perspectives and backgrounds.
+- **Be community-oriented:** Encourage collaboration, help others when you can, and gracefully accept constructive criticism.
+- **Speak Up:** If you witness inappropriate behavior, report it.
+
+You are expected to read and understand the full [CoC](https://github.com/asyncapi/community/blob/master/CODE_OF_CONDUCT.md) before contributing.
+
+
+## What to Do If You Experience or Witness a Violation
+
+If you experience or observe discrimination, harassment, or any behavior that violates the CoC:
+
+### 1. Document What Happened
+- Note what was said or done
+- Include context (e.g., link to a GitHub issue, Slack conversation)
+- If possible, take a screenshot
+
+### 2. Report the Incident
+You can report a CoC violation by:
+
+- Emailing **conduct@asyncapi.io** – this forwards directly to the [Code of Conduct Committee](https://github.com/asyncapi/community/blob/master/code_of_conduct/code-of-conduct-committee.md)
+- Reaching out to a specific CoC Committee member if the issue involves someone on the committee
+
+All reports are handled with confidentiality, respect, and prompt action.
+
+
+## Conflict Resolution
+
+Not all disagreements are violations. When conflicts happen:
+
+- First, try a respectful discussion or ask a neutral contributor to help mediate.
+- If the situation escalates or becomes hostile, report the issue to the CoC Committee.
+
+The Code of Conduct Committee is trained to resolve conflicts fairly and ensure everyone feels safe.
+
+
