+tags: |
+  # dynamically set the branch name as a prefix
+  type=sha,prefix={{branch}}-
+  # dynamically set the branch name and sha as a custom tag
+  type=raw,value=mytag-{{branch}}-{{sha}}
+```
+
+### Major version zero
+
+Major version zero (`0.y.z`) is for initial development and **may** change at any time. This means the public API
+[**should not** be considered stable](https://semver.org/#spec-item-4).
+
+In this case, Docker tag `0` **should not** be generated if you're using [`type=semver`](#typesemver) with `{{major}}`
+pattern. You can manage this behavior like this:
+
+```yaml
+# refs/tags/v0.1.2
+tags: |
+  # output 0.1.2
+  type=semver,pattern={{version}}
+  # output 0.1
+  type=semver,pattern={{major}}.{{minor}}
+  # disabled if major zero
+  type=semver,pattern={{major}},enable=${{ !startsWith(github.ref, 'refs/tags/v0.') }}
+```
+
+### JSON output object
+
+The `json` output is a JSON object composed of the generated tags and labels so that you can reuse them further in your
+workflow using the [`fromJSON` function](https://docs.github.com/en/actions/learn-github-actions/expressions#fromjson):
+
+```yaml
