 First I would recommend you to install Raspbian to the RPi.

-Under the **RPi Setup** section on this page, I will be including an extra explanation here where some specifics apply to the RPi.

 I was inspired by the awsome work of **[William Halley in his blog](https://www.willhaley.com/blog/raspberry-pi-wifi-ethernet-bridge/)**, where I was able to follow succesfully the option 2 that it is proposed: *to share Wifi through Ethernet on a separated subnet*.
