Hi Arturo! There are a number of new initiatives to help new users get the information they need, but they're all brand new and just getting started. I'm part of Project Newbie and will help you in any way I can.
Start with The Steemprentice FAQ
If you still have questions, you can ask them here and I'll reply, or you can start Steemit chat via the menu in the upper right hand corner. Feel free to direct message me through chat. Or you can ask questions in the channel called "general."
Welcome to Steemit!
