+## Folder Structure of Create React App
+`create-react-app` is a monorepo, meaning it is divided into independent sub-packages.<br>
+These packages can be found in the [`packages/`](https://github.com/facebookincubator/create-react-app/tree/master/packages) directory.
+
+### Overview of directory structure
+```
+packages/
+  babel-preset-react-app/
+  create-react-app/
+  eslint-config-react-app/
+  react-dev-utils/
+  react-scripts/
+```
+### Package Descriptions
+#### [babel-preset-react-app](https://github.com/facebookincubator/create-react-app/tree/master/packages/babel-preset-react-app)
+This package is a babel preset intended to be used with `react-scripts`.<br>
+It targets platforms that React is designed to support (IE 9+) and enables experimental features used heavily at Facebook.<br>
+This package is enabled by default for all `create-react-app` scaffolded applications.
+#### [create-react-app](https://github.com/facebookincubator/create-react-app/tree/master/packages/create-react-app)
+The global CLI command code can be found in this directory, and shouldn't often be changed. It should run on Node 0.10+.
+#### [eslint-config-react-app](https://github.com/facebookincubator/create-react-app/tree/master/packages/eslint-config-react-app)
+This package contains a conservative set of rules focused on making errors apparent and enforces no style rules.<br>
+This package is enabled by default for all `create-react-app` scaffolded applications.
+#### [react-dev-utils](https://github.com/facebookincubator/create-react-app/tree/master/packages/react-dev-utils)
+This package contains utilities used for `react-scripts` and sister packages.<br>
+Its main purpose is to conceal code which the user shouldn't be burdened with upon ejecting.
+#### [react-scripts](https://github.com/facebookincubator/create-react-app/tree/master/packages/react-scripts)
+This package is the heart of the project, which contains the scripts for setting up the development server, building production builds, configuring all software used, etc.<br>
+All functionality must be retained (and configuration given to the user) if they choose to eject.

 1. Tag all merged pull requests that go into the release with the relevant milestone. Each merged PR should also be labeled with one of the [labels](https://github.com/facebookincubator/create-react-app/labels) named `tag: ...` to indicate what kind of change it is.
