Hey could you assign me this?

Hey!

For sure I can assign you this issue, however I faced and face still today issues some GitHub users, human or not, wanting to grab the issue but without providing real and useful implementation. In the end, assigning an issue does not matter, only matters the contribution.

So, before I assign you this issue, I need several details from you:

1. Do you have any question about this issue?
2. How do you think the implementation?
3. How can I test it?
4. Which things do you need?
