I’m writing a book! (pleas help)

Hello!! I’m starting (for real) the process of writing my own book! Its in a dystopian post- apocolyptic world following a group of people traveling and meeting different obsticals along the way.

Yea i know it sound very simple and boring right now but i promise i have a bunch of notes and ideas for this story.

What i’m asking for is help! English is not my first language (as you might be able to tell) and i am younger than 20 sooo i’m going to need some help in this writing process.
Stuff like Names, places, personalitys and a bunch of things relevant to writing in a post apocolyptic world are going to need a couple more sets of eyes.

Basiaclly what i am asking is that if YOU reading this want to follow along and help me on this journey i would be incredibly gratefull!!
