Introducing a package manager into your project introduces a new workflow
around dependencies. Yarn tries its best to stay out of your way and make each
step of this workflow simple to understand.

There are a few things you should know about the basic workflow:

1. Creating a new project
2. Adding/updating/removing dependencies
3. Installing/reinstalling your dependencies
4. Working with version control (e.g. git)
5. Continuous Integration
