Hi @antonioolf i am intrested in doing it... could you please assign it to me

[LuizHAP]

I'm doing the code translation

[antonioolf]

@nexuspy and @LuizHAP both can do the translation and create a PR to master. I will mark both as approved (as long as they have quality).
In the end I can choose one to merge.

In this way the two will have their contributions eligible for the hacktoberfest.
