+# Comet Release Process
+
+This documentation is for creating an official source release of Apache DataFusion Comet. It does not currently 
+cover creating binary releases.
+
+The release process is based on the parent Apache DataFusion project, so please refer to the 
+[DataFusion Release Process](https://github.com/apache/datafusion/blob/main/dev/release/README.md) for detailed 
+instructions if you are not familiar with the release process here.
+
+Here is a brief overview of the steps involved in creating a release:
+
+- Create and merge a PR to update the version & update the changelog
+- Tag the release with a release candidate tag e.g. 0.1.0-rc1
+- Run the create-tarball script to create the source tarball and upload it to the dev site
+- Start an email voting thread
+- Once the vote passes, run the release-tarball script to move the tarball to the release site
+
+## Verifying Release Candidates
+
+The vote email will link to this section of this document, so this is where we will need to provide instructions for
+verifying a release candidate.
+
+The `dev/release/verify-release-candidate.sh` is a script in this repository that can assist in the verification 
+process. It checks the hashes and runs the tests.
+
+```shell
+./dev/release/verify-release-candidate.sh 0.1.0 1
+```

+Subject: [VOTE] Release Apache DataFusion Comet ${version} RC${rc}
+Hi,
+
+I would like to propose a release of Apache DataFusion Comet version ${version}.
+
+This release candidate is based on commit: ${release_hash} [1]
+The proposed release tarball and signatures are hosted at [2].
+The changelog is located at [3].
+
+Please download, verify checksums and signatures, run the unit tests, and vote
+on the release. The vote will be open for at least 72 hours.
+
+Only votes from PMC members are binding, but all members of the community are
+encouraged to test the release and vote with "(non-binding)".
+
+The standard verification procedure is documented at https://github.com/apache/datafusion-comet/blob/main/dev/release/README.md#verifying-release-candidates.
+
+[ ] +1 Release this as Apache DataFusion Comet ${version}
+[ ] +0
+[ ] -1 Do not release this as Apache DataFusion Comet ${version} because...
+
+Here is my vote:
+
++1
+
+[1]: https://github.com/apache/datafusion-comet/tree/${release_hash}
