+# Create Next App [![NPM](https://img.shields.io/npm/v/@create-next-app/core.svg)](https://www.npmjs.com/package/@create-next-app/core)
+
+Create Next App allows you to create a [Next.js](https://nextjs.org) app by running one command. It come with default, material, bootstrap, semantic... templates, Next.js examples and Next.js CMS.
+
+## Features
+
+  - Standard Template – providing a way to create your app with standard templates such as default, material, bootstrap, semantic, ... etc.
+  - Standard Example – providing a way to bootstrap your app with standard examples such as basic css, typescript, next css, next routes, redux, ... etc.
+  - Standard CMS – comming soon...
+
+## Installation
+
+Create Next App can be installed via npm:
+
+```
+npm install --global @create-next-app/core
+```
+
+Create Next App can be installed via yarn:
+
+```
+yarn global add @create-next-app/core
+```
+
+## To learn how to use Create Next App
+
+- [Home](https://create-next-app.js.org)
+- [Templates](https://create-next-app.js.org/get-started-with-templates)
+- [Examples](https://create-next-app.js.org/get-started-with-examples)
+
+<!-- ## Install
+
+To use create-next-app command line interface you have to install `create-next-app`.
+
+create-next-app is available on npm. It can be installed with the following command:
+
+```
+npm install --global create-next-app
+```
+
+create-next-app is available on yarn as well. It can be installed with the following command:
+
+```
+yarn global add create-next-app
+```
+
+You don't need to install or setup Webpack or Babel. They come with Next.js, so you can just start coding after running create-next-app command line.
+
+## Create a Next App in seconds
+
+To create a new Next.js app called <i>my-app</i> with `default` or `material` or `bootstrap` or `semantic` templates.
+
+1. Go to [Create Next App templates](https://create-next-app.js.org/#templates)
+2. Choose a template to create your Next.js app (such as default)
+3. And then run `create-next-app my-app --template default`
+4. Well done!
+
+It will create a directory called <i>my-app</i> inside the current folder.
+Inside that directory, it will generate the initial project structure and install the transitive dependencies:
+
+```
+.
+├── README.md
+├── components
+│   ├── head.js
+│   └── nav.js
+├── next.config.js
+├── node_modules
+│   ├── [...]
+├── package.json
+├── pages
+│   └── index.js
+├── static
+│   └── favicon.ico
+└── yarn.lock
+```
+
+No configuration or complicated folder structures, just the files you need to build your app. When the installation is done, you can open your project folder, run this command:
+
+```
+cd my-app
+```
+
+Inside the newly created project, you can run some built-in commands:
+
+### `npm run dev` or `yarn dev`
+
+Runs the app in development mode.<br/>
+Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
+
+The page will automatically reload if you make changes to the code.<br>
+You will see the build errors and lint warnings in the console.
+
+Out of the box, we get:
+
+  - Automatic transpilation and bundling (with webpack and babel)
+  - Hot code reloading
+  - Server rendering and indexing of `./pages`
+  - Static file serving. `./static/` is mapped to `/static/`
+
+### `npm run build` or `yarn build`
+
+Builds the app for production to the `.next` folder.<br/>
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+### `npm run start` or `yarn start`
+
+Starts the application in production mode. The application should be compiled with `npm run build` first.
+
+Now you maybe ready to code and deploy your app!
+
+## Start Next Examples
+
+There are a bunch of examples in the Next.js repository that you can use to bootstrap your app.
+
+To bootstrap your app with example:
+
+1. Go to [Create Next App examples](https://create-next-app.js.org/#examples)
+2. Choose an example to bootstrap your app (such as basic-css)
+3. And then run `create-next-app my-app --example basic-css`
+4. Well done!
+
+Now you maybe ready to code and deploy your app!
+
+## User Guide
+
+You can find detailed instructions on using Next.js and many tips in [its documentation](https://nextjs.org/docs/). -->
