-Students should use this [rubric](https://review.udacity.com/#!/projects/2696458597/rubric) for self-checking their submission. Make sure the functions you write are **object-oriented** - either class functions (like Player and Enemy) or class prototype functions such as Enemy.prototype.checkCollisions, and that the keyword 'this' is used appropriately within your class and class prototype functions to refer to the object the function is called upon. Also be sure that the **readme.md** file is updated with your instructions on both how to 1. Run and 2. Play your arcade game.
+## What's This? 这是什么项目？
 
-For detailed instructions on how to get started, check out this [guide](https://docs.google.com/document/d/1v01aScPjSWCCWQLIpFqvg3-vXLH2e8_SZQKC8jNO0Dc/pub?embedded=true).
+This is the first project of the Udacity Frontend(Advanced) Nanodegree Arcade Game, which is mainly used for teaching the students to write object-oriented JavaScript code. 这是 Udacity 前端进阶纳米学位的第一个项目：Arcade Game。项目主要是用于训练学生编写面向对象的 JavaScript 代码的能力。
+
+## How to Run This? 如何运行项目？
+
+One of the easiest way to get this project up and running is to serve the `index.html` file in the root to a specific local port through static servers so that you can visit. I used the `http-server` written in NodeJS but feel free to use any others as you like or are more familiar to. 运行项目一个最简单的方法，就是本地起一台静态服务器，并把根目录下的 `index.html` 暴露到本地的一个端口以供访问。这里我使用的是 NodeJS 写的一个 `http-server`，不过你可以使用其他任何你更喜欢或熟悉的服务器，它们的作用应是相同的。
+
+Make sure you have `npm` or `yarn` installed globally in your machine. If not, please reference the following sections to install them. 首先请确保你本地安装了全局的 `npm` 或 `yarn`。如果没有，请参考下面内容进行安装。
+
+Having npm/yarn installed globally and correctly, please run the following commands to start the game: 正确安装完 npm/yarn 之后，请运行下面的命令以启动游戏：
+
+```bash
+npm install -g http-server
+cd frontend-nanodegree-arcade-game  # Make sure you run the following command in the project root 运行下面的命令前，请确保你已经在项目的根目录下
+http-server -c-1 -o # -c-1 disables caches, -o will open the browser right after server started -c-1 会禁用缓存，-o 会在服务器启动后直接打开浏览器
+```
+
+### How to install NPM globally? 如何安装全局的 NPM
+
+* Install through the archives: Go to the [Node.js official](https://nodejs.org/en/),download the latest archives, and install it by double click after downloaded 通过安装包安装：进行 [Node.js 的官网](https://nodejs.org/en/)，下载最新版本的安装包，下载完成后双击安装
+* Install through nvm: Follow the instructions in the [nvm repo](https://github.com/creationix/nvm), or reference [this article](https://www.digitalocean.com/community/tutorials/how-to-install-node-js-with-nvm-node-version-manager-on-a-vps) 通过 nvm 安装：请参考 [nvm 仓库](https://github.com/creationix/nvm) 的文档，或参考 [这篇文章](https://www.digitalocean.com/community/tutorials/how-to-install-node-js-with-nvm-node-version-manager-on-a-vps)
+
+### How to install yarn globally? 如何安装全局的 yarn
+
+```bash
+npm install -g yarn
+```
+
+This requires a globally installed npm. 这需要你先安装了一个全局的 npm。
