+# Release Procedure
+
+
+## Steps
+
+The following are the steps to follow to make a release of Arduino App CLI:
+
+### 1. Create the pre-release on GitHub
+
+You need to **create and push the new tag** and wait for the pre-release to appear on [the "**Releases**" page](https://github.com/arduino/arduino-app-cli/releases).
+
+
+1. Checkout the release branch in the repository.
+1. Run the following commands:
+   ```text
+   git pull
+   git tag -a <YOUR_VERSION> -m "<YOUR_VERSION>"
+   git push origin <YOUR_VERSION>
+   ```
+
+Pushing a tag will trigger a **GitHub Actions** workflow on the `main` branch. Check the "**Arduino App CLI**" workflow and see that everything goes right. If the workflow succeeds, a new pre-release will be created automatically and you should see it on the ["**Releases**"](https://github.com/arduino/arduino-app-cli/releases) page.
+
+### 2. ✅ Validate the pre-relaese
+
+- Ask in the  #ft_swc_qa_requests Slack channel to perform QA testing
+- Write a message in the #general Slack channel:
+
+
+### 3. 🚢 Create the release on GitHub
+
+### 4. 📄 Create the changelog
+
+Edit the `CHANGELOG.md` file following the **Keep A Changelog** scheme:
+
+https://keepachangelog.com/en/1.0.0/#how

+- Submitted an issue that was resolved
+- Provided valuable assistance with the investigation of an issue that was resolved
+
+Add a "**Known Issues**" section at the bottom of the changelog.
+
+
+
+### 3. 😎 Brag about it
+- Write a message in the `#ft_swc_deploy` **Slack** channel:

+  >
