If there's a web page that will tell something needed then I hope you don't expect it needs to be replicated here instead of someone here giving a link to there?
If you understood the tutorial you wouldn't have asked the question (a reasonable assumption.)
It would be reasonable to assume that specific questions should be asked about what is not understood.
If you can't read words the you should be learning the alphabet, not sentence structure and grammer let alone "I'm totally new to code, help me with my GPS Ethernet car autopilot novel".
