+  If you want to use full semantic versioning for the `engines` field, you can enable the `updaters.engines.fullVersion` input.
+  ```yaml
+  - uses: hongaar/update-node-versions@v2
+    with:
+      updaters.engines.fullVersion: true
+  ```
+  This will update the `engines` field to include the full version.
