+### 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.') }}
+```
