+## Components of the System
+
+### CLI
+
+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`.
+
+### CLI Service
+
+The CLI Service (`@vue/cli-service`) is a development dependency. It's an npm package installed locally into every project created by `@vue/cli`.
+
+The CLI Service is built on top of [webpack](https://webpack.js.org/) and [webpack-dev-server](https://github.com/webpack/webpack-dev-server). 
+
+### CLI Plugins
+
+CLI Plugins are npm packages that provide optional features to your Vue CLI projects, such as Babel/TypeScript transpilation, ESLint integration, unit testing, and end-to-end testing. It's easy to spot a Vue CLI plugin as their names start with either `@vue/cli-plugin-` (for built-in plugins) or `vue-cli-plugin-` (for community plugins).
