There are several moving parts of Vue CLI - if you look at the [source code](https://github.com/vuejs/vue-cli/tree/dev/packages/%40vue), you will find that it is a monorepo containing a number of separately published packages.

The CLI (`@vue/cli`) is a globally installed npm package and provides the `vue` command in your terminal. It provides the ability to quickly scaffold a new project via `vue create`, or instantly prototype new ideas via `vue serve`. You can also manage your projects using a graphical user interface via `vue ui`. We will walk through what it can do in the next few sections of the guide.
