+> Having a reproducible example highly reduces the time to resolution, allows others to participate, and avoids misunderstandings/communications cycles.
+You can support by adjusting one of the [springwolf examples](https://github.com/springwolf/springwolf-core/tree/master/springwolf-examples), so that it reproduces your scenario:
+> 1. Fork this repo (`springwolf-core`) in GitHub and `git clone` it
+> 2. Adjust classes, etc. in one of the `springwolf-examples`
+> 3. Push your local changes to a branch on your fork (`git commit`, `git push`)
+> 4. Open a `Pull Request` (a notification will appear in your fork as soon as you push your branch), the title should include `reproduce` and ideally the link to the issue.
