+# "Release" workflow
+
+Make a [GitHub release](https://docs.github.com/en/github/administering-a-repository/releasing-projects-on-github/about-releases) with changelog on release [tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging) push.
+
+## Installation
+
+### Workflow
+
+Install the [`release-tag.yml`](release-tag.yml) GitHub Actions workflow to `.github/workflows/`
+
+### Readme badge
+
+Markdown badge:
+
+```markdown
+[![Release status](https://github.com/REPO_OWNER/REPO_NAME/actions/workflows/release-tag.yml/badge.svg)](https://github.com/REPO_OWNER/REPO_NAME/actions/workflows/release-tag.yml)
+```
+
+Replace the `REPO_OWNER` and `REPO_NAME` placeholders in the URLs with the final repository owner and name ([example](https://raw.githubusercontent.com/arduino-libraries/ArduinoIoTCloud/master/README.md)).
+
+---
+
+Asciidoc badge:
+
+```adoc
+image:https://github.com/{repository-owner}/{repository-name}/actions/workflows/release-tag.yml/badge.svg["Release status", link="https://github.com/{repository-owner}/{repository-name}/actions/workflows/release-tag.yml"]
+```
+
+Define the `{repository-owner}` and `{repository-name}` attributes and use them throughout the readme ([example](https://raw.githubusercontent.com/arduino-libraries/WiFiNINA/master/README.adoc)).
+
+## Commit message
+
+```
+Add GitHub Actions workflow to generate releases
+
+On every push of a release tag (e.g., "1.2.3" or "v1.2.3") to the repository, create a GitHub release with a raw
+changelog generated from the commit history since the last release tag.
+
+Tags that contain a pre-release version will cause the GitHub release to be marked as a pre-release.
+```
+
+## PR message
+
+```markdown
+On every push of a release tag (e.g., `1.2.3` or `v1.2.3`) to the repository, create a [GitHub release](https://docs.github.com/en/github/administering-a-repository/releasing-projects-on-github/about-releases) with a raw [changelog generated](https://github.com/arduino/create-changelog) from the commit history since the last release tag.
+
+Tags that contain a [pre-release version](https://semver.org/#spec-item-9) will cause the GitHub release to be marked as a pre-release.
