+# Contributing to Apache DataFusion Comet
+
+We welcome contributions to Comet in many areas, and encourage new contributors to get involved.
+
+Here are some areas where you can help:
+
+- Testing Comet with existing Spark jobs and reporting issues for any bugs or performance issues
+- Contributing code to support Spark expressions, operators, and data types that are not currently supported
+- Reviewing pull requests and helping to test new features for correctness and performance
+- Improving documentation
+
+## Finding issues to work on
+
+We maintain a list of good first issues in GitHub [here](https://github.com/apache/datafusion-comet/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
+
+## Reporting issues
+
+We use [GitHub issues](https://github.com/apache/datafusion-comet/issues) for bug reports and feature requests.
+
+## Asking for Help
+
+The Comet project uses the same Slack and Discord channels as the main Apache DataFusion project. See details at
+[Apache DataFusion Communications]. There are dedicated Comet channels in both Slack and Discord.
+
+## Regular public meetings
+
+The Comet contributors hold regular video calls where new and current contributors are welcome to ask questions and
+coordinate on issues that they are working on.
+
+See the [Apache DataFusion Comet community meeting] Google document for more information.
