+Follow the steps below exactly to avoid a broken release.
+
+1. Adapt version information.
+   The CI pipeline will fail if the version strings in the files below do not match.
+   * `nitrokeyapp/VERSION` (mind the final newline)
+   * `pyproject.toml` 
+   * `ci-scripts/linux/rpm/nitrokey-app2.spec` 
+   * Add flatpak meta-data in `meta/com.nitrokey.nitrokey-app2.metainfo.xml`, 
+     like this: `<release version="2.3" date="2024-04-19"/>` 
+     * The latest release should be on top of this list.
+2. Create a new tag and release.
+   1. Make sure the `main` branch of your cloned repository is up-to-date.
+      Create a new tag with `git tag -S -m "vX.Y.Z" vX.Y.Z` and push it to GitHub with `git push --tags`.
+      Open the repository on GitHub and open the releases page.
+      Click "Draft a new release" and select the just created tag.
+   2. Open the repository on GitHub and open the releases page.
+      Click "Draft a new release".
+      In the dropdown field "Choose a tag" select "Create a new tag".
+      Enter the version string in the form `vX.Y.Z`.
+   Fill the fields title and description.
+   Set the checkbox "Set as a pre-release" or "Set as the latest release".
+   A pre-release can still be safely removed, a latest release can not be removed anymore.
+3. Wait for the pipelines to succeed.
+   At this point the tag and release can still be removed.
+   Continue only when the pipelines succeded and manual test are fine.
+4. Open the release page for the version and click the edit button.
+   Change the release from pre-release to latest release.
+5. Download the Windows artifacts ending in `_unsigned.exe` and `_unsigned.msi`.
+   Sign the artifacts and upload them afterwards, deleting the unsigned artifacts.
+6. Please mind that Flatpak and RPM COPR builds needs to be triggered manually.
+
+The release is now complete.
