When you start programming half the battle is getting your bearings. Suddenly it matters where you put your files. You need to know where you home directory is, you need to understand file permissions, you need to understand what a file actually *is*.

Fortunately we can do some things to make your life easier. We can install an IDE: a program that lets you visualize your files and folders and quickly switch between them. We can install a version control system that will let you "snapshot" your code and save it to the cloud so you never lose it. We can organize our project to be repeatable, and more importantly, unloseable. Fortunately we can do some things to make your life easier.

### Install VSCode
Your most important tool as a programmer is a proper editor. It should offer you a wide selection of tools but get out of your way when you don't need it. VSCode is a great option in 2020. It has tons of extensions and support for almost every language you can throw at it. Your most important tool as a programmer is a proper editor.
