Working on a Book/Website about Windows 10 Mobile, looking for suggestions

[Darthbobcat]

I'm currently finishing up a Coding Bootcamp, and I decided that I would put my new skills to use with an informative website (which will be fairly easy to convert into an e-book) about how to use Windows 10 mobile. I figured that this is the best place to go for some opinions. I just had the idea today and I sat down to write the intro, some of the second to last chapter on Windows Insider and broke down different chapter topics I would talk about.

Is there anything obvious I'm missing? Here's a read only link to my OneDrive, where I have the document. http://1drv.ms/1WGJaSF

Thanks for the feedback in advance!
