+# Release Guide 
+
+This document describes how to release Dapr Components Contrib along with associated artifacts.
+
+## Prerequisites
+
+Only maintainers and the release team should run releases.
+
+## Pre-release
+
+Pre-releases use tags like `v1.11.0-rc.0`, `-rc.1`, and so on. They are created through the GitHub Actions workflow.
+
+### Steps
+
+1. Update the Dapr runtime and dashboard versions in workflows or tests if needed. Merge that change to master.
+
+2. Open GitHub Actions and click the **create-release** workflow.
+
+3. Press the **Run workflow** button.
+   The workflow will:
+
+   * create the `release-<major>.<minor>` branch
+   * create the pre-release tag
+   * build the artifacts
+
+4. Test the produced build.
+
+5. If there are issues, fix them in the release branch and trigger the workflow again by creating a new pre-release tag (for example `-rc.1`).
+
+6. Repeat until the build is good.
+
+## Stable Release
+
+Create a stable tag without the rc suffix (for example `v1.11.0`).
+CI will build and publish the release.
+
+## Patch Releases
+
+Use the existing release branch.
+Create a new pre-release tag like `v1.11.1-rc.0`, test it, and when ready tag the stable version `v1.11.1`.
+CI will build and publish it.
+
+## Project Release Guidelines
+
+See [this document](https://github.com/dapr/community/blob/master/release-process.md) for the project's release process and guidelines.
