 # Releasing with the SCM Version Provider
 
+In this tutorial, you will learn how to bump the version using the `scp` version provider; as you can't use `cz bump`.
+
 ## About
 
 When `version_provider` is set to `scm`, Commitizen reads the version directly from your Git tags instead of a config file.

+To release a new version without an extra commit and using tags,
+you can compute the next tag using `cz version` and then, you can manually create the tag directly.
+
+In this example, we create an annotated tag with the changelog as the tag message, using just `git`.
 
 ```sh
 next_version=$(cz version --project --next --tag)
-git tag --annotate "$next_version" --message "$next_version"
+cz changelog --incremental --dry-run --unreleased-version "$next_version" > .changelog.md
+git tag --annotate "$next_version" -F .changelog.md
 git push --follow-tags
 ```
 
 !!! tip
     Wrap this in a CI job to fully automate releases when using the `scm` provider using [setup-cz](https://github.com/commitizen-tools/setup-cz)
 
-## Why Can't I Bump with SCM?
-
-When you run `cz bump`, Commitizen normally creates a new commit that updates the version somewhere,
-either in `.cz.toml`, or in `pyproject.toml` if you're using Python, or `Cargo.toml` for rust.
-It may also update `version_files` and regenerate `CHANGELOG.md`.
-
-Commitizen deliberately bundles a new release into a single commit.
-This is core to its philosophy: the version should live in the code itself, not only in a Git tag,
-so anyone can read the current version straight from the source, without needing to inspect the tags.
-When a Git tag is the sole source of truth, that guarantee disappears,
-the version becomes metadata layered on top of your history instead of something visible within the code itself.
