Ok, so, you might know about JavaScript regular expressions. Well, here is a tutorial about them, but written by a 13 year old, so it isn't actually any good!

Regular expressions go between / characters. Here is an exampe, /hi/.

Ok, now then. Let's learn how to match the string abc. Well, that's quite simple.

/abc/. Yey! So putting letters next to each other makes them match one after the other.

Ok, now, after the second / we can put a g to make it match globally, that is, we can extract abc from xyzabcghi.

These instructions will not work on Chromebooks with an ARM processor. If you have an ARM processor then you cannot install Chromebrew to get git. You'll need to instead install crouton. Here are instructions that you can follow: https://github.com/macton/arch-linux-install-notes/tree/master/arm-chromebook-chroot

#Configuring Chromebook for Development

After a full Sunday of trial and error, and stepping through many semi-complete or dated blog posts explaining how to do this, I was able to get the Chromebook into developer mode, install git, Node.js, and NPM.

Here's what I did...

1. Enable Developer Mode

• Press Esc-Refresh-Power keys which will reboot the Chromebook
