-[中文简介](README_ZH.md)
-
-Nightingale is a fork of Open-Falcon, and all the core modules have been greatly optimized. It integrates the best practices of DiDi. You can think of it as the next generation of Open-Falcon, and use directly in production environment.
-
-## Documentation
-
-Nightingale user manual: [https://n9e.didiyun.com/](https://n9e.didiyun.com/)
-
-## Compile
-
-```bash
-mkdir -p $GOPATH/src/github.com/didi
-cd $GOPATH/src/github.com/didi
-git clone https://github.com/didi/nightingale.git
-cd nightingale
-./control build
-```
-
-## Quickstart with Docker
-
-We has offered a Docker demo for the users who want to give it a try. Before you get started, make sure you have installed **Docker** & **docker-compose** and there are some details you should know.
-
-* We highly recommend users prepare a new VM environment to use it.
-* All the core components will be installed on your OS according to the `docker-compose.yaml`.
-* Nightingale will use the following ports, `80`, `5800`, `5810`, `5811`, `5820`, `5821`, `5830`, `5831`, `5840`, `5841`, `6379`, `2058`, `3306`.
-
-Okay. Run it! Once the docker finish its jobs, visits http://your-env-ip in your broswer. Default username and password is `root:root`.
-```bash
-$ docker-compose up -d
-```

-[English Introduction](README.md)
-
-Nightingale 是一套衍生自 Open-Falcon 的互联网监控解决方案，融入了部分滴滴生产环境的最佳实践，灵活易用，稳定可靠，是一个生产环境直接可用的版本 :-)
-
-## 文档
-
-使用手册请参考：[夜莺使用手册](https://n9e.didiyun.com/)
-
-## 编译
-
-```bash
-mkdir -p $GOPATH/src/github.com/didi
-cd $GOPATH/src/github.com/didi
-git clone https://github.com/didi/nightingale.git
-cd nightingale
-./control build
-```
-
-## 快速开始
-
-使用 docker 和 docker-compose 环境可以快速部署一整套 nightingale 系统，涵盖了所有的核心组件。
-
-* 强烈建议使用一个新的虚拟环境来部署和测试这个系统。
-* 系统组件占用了以下端口，`80`, `5800`, `5810`, `5811`, `5820`, `5821`, `5830`, `5831`, `5840`, `5841`, `6379`, `2058`, `3306`，部署前请确保这些端口没有被使用。
-
-
-使用 docker-compose 一键构建部署，完成以后可以使用浏览器打开 http://your-env-ip。 默认的登录账号密码均为 `root`。
-```bash
-$ docker-compose up -d
-```
