+# Contributor Covenant Code of Conduct
+
+## TL;DR
+
+Common sense rules. Treat people the same way you want to be treated.
+
+## Detail
+
+This is an open source project. Everyone and anyone is welcome to contribute
+to it as much or as little as they want to.
+
+Personal views of contributors have no effect on the project and should be
+kept in the personal realm not this project.
+
+It is a requirement to treat other contributors as well as maintainers with
+respect, when communicating in the realm of this project. It is OK to agree to
+disagree.
+
+## Conflict
+
+If ever conflict arises, please bring it to the attention of the maintainers
+privately. You can always find us on our [Discord](https://phalcon.io/discord)
+server or you can send us an email at [email protected]
+
+The core team maintains the final decision on any conflict that may arise.
