This will be how we will edit the code. It's lightweight and pretty awesome.
Git is a way to share and collaborate on our code. It can be really confusing but is very powerful. Make sure to check the boxes it prompts. I would check them all but ESPECIALLY the one that adds git to your PATH.
Things to get via the command line
npm install -g @angular/cli. This will use the node package manager (mentioned above) to install the Angular CLI (command line interface) globally. Meaning it can be accessed from anywhere in the command line and you won't have to be in any specific folder/project.
