+## Releasing
+
+To cut a [release](https://github.com/cipherstash/encrypt-query-language/releases) of EQL:
+
+1. Draft a [new release](https://github.com/cipherstash/encrypt-query-language/releases/new) on GitHub
+1. Choose a tag, and create a new one with the prefix `eql-` followed by a [semver](https://semver.org/) (for example, `eql-1.2.3`)
+1. Generate the release notes
+1. Optionally set the release to be the latest (you can set a release to be latest later on if you are testing out a release first)
+1. Click the `Publish release` button
+
+This will trigger a run of the [Release EQL](https://github.com/cipherstash/encrypt-query-language/actions/workflows/release-eql.yml) workflow, which will build and attach artifacts to the release.
