Hello! Any news on this topic?

[tbak]

Sorry, we have been busy recently. Would you like to make a PR for this?

[kennedyoliveira]

I would love to, but don't know how can i make it, if you give me some hints, i don't understand the eureka server, well didn't looked at the source through.

Anyway, i'll try, but would be very helpful if you could give me some advices.

Thank you!
