+# TDengine 简介
+
+TDengine是涛思数据专为物联网、车联网、工业互联网、IT运维等设计和优化的大数据平台。除核心的快10倍以上的时序数据库功能外，还提供缓存、数据订阅、流式计算等功能，最大程度减少研发和运维的复杂度，且核心代码，包括集群功能全部开源（开源协议，AGPL v3.0）。
+
+- 10 倍以上性能提升。定义了创新的数据存储结构，单核每秒就能处理至少2万次请求，插入数百万个数据点，读出一千万以上数据点，比现有通用数据库快了十倍以上。
+- 硬件或云服务成本降至1/5。由于超强性能，计算资源不到通用大数据方案的1/5；通过列式存储和先进的压缩算法，存储空间不到通用数据库的1/10。
+- 全栈时序数据处理引擎。将数据库、消息队列、缓存、流式计算等功能融合一起，应用无需再集成Kafka/Redis/HBase/Spark等软件，大幅降低应用开发和维护成本。
+- 强大的分析功能。无论是十年前还是一秒钟前的数据，指定时间范围即可查询。数据可在时间轴上或多个设备上进行聚合。即席查询可通过Shell/Python/R/Matlab随时进行。
+- 与第三方工具无缝连接。不用一行代码，即可与Telegraf, Grafana, EMQ X, Prometheus, Matlab, R集成。后续还将支持MQTT, OPC, Hadoop，Spark等, BI工具也将无缝连接。
+- 零运维成本、零学习成本。安装、集群一秒搞定，无需分库分表，实时备份。标准SQL，支持JDBC,RESTful，支持Python/Java/C/C++/Go/Node.JS, 与MySQL相似，零学习成本。
+
+# 文档
+
+TDengine是一个高效的存储、查询、分析时序大数据的平台，专为物联网、车联网、工业互联网、运维监测等优化而设计。您可以像使用关系型数据库MySQL一样来使用它，但建议您在使用前仔细阅读一遍下面的文档，特别是 [数据模型](https://www.taosdata.com/cn/documentation/architecture) 与 [数据建模](https://www.taosdata.com/cn/documentation/model)。除本文档之外，欢迎 [下载产品白皮书](https://www.taosdata.com/downloads/TDengine%20White%20Paper.pdf)。
+
+# 生成
+
+TDengine目前2.0版服务器仅能在Linux系统上安装和运行，后续会支持Windows、macOS等系统。客户端可以在Windows或Linux上安装和运行。任何OS的应用也可以选择RESTful接口连接服务器taosd。CPU支持X64/ARM64/MIPS64/Alpha64，后续会支持ARM32、RISC-V等CPU架构。用户可根据需求选择通过[源码](https://www.taosdata.com/cn/getting-started/#通过源码安装)或者[安装包](https://www.taosdata.com/cn/getting-started/#通过安装包安装)来安装。本快速指南仅适用于通过源码安装。
+
+## 安装工具
+
+### Ubuntu 16.04 及以上版本 & Debian：
+
+```bash
+sudo apt-get install -y gcc cmake build-essential git
+```
+
+### Ubuntu 14.04：
+
+```bash
+sudo apt-get install -y gcc cmake3 build-essential git binutils-2.26
+export PATH=/usr/lib/binutils-2.26/bin:$PATH
+```
+
+编译或打包 JDBC 驱动源码，需安装 Java JDK 8 或以上版本和 Apache Maven 2.7 或以上版本。
+
+安装 OpenJDK 8：
+
+```bash
+sudo apt-get install -y openjdk-8-jdk
+```
+
+安装 Apache Maven：
+
+```bash
+sudo apt-get install -y  maven
+```
+
+### CentOS 7：
+
+```bash
+sudo yum install -y gcc gcc-c++ make cmake git
+```
+
+安装 OpenJDK 8：
+
+```bash
+sudo yum install -y java-1.8.0-openjdk
+```
+
+安装 Apache Maven：
+
+```bash
+sudo yum install -y maven
+```
+
+### CentOS 8 & Fedora:
+
+```bash
+sudo dnf install -y gcc gcc-c++ make cmake epel-release git
+```
+
+安装 OpenJDK 8：
+
+```bash
+sudo dnf install -y java-1.8.0-openjdk
+```
+
+安装 Apache Maven：
+
+```bash
+sudo dnf install -y maven
+```
+
+## 获取源码
+
+首先，你需要从 GitHub 克隆源码：
+
+```bash
+git clone https://github.com/taosdata/TDengine.git
+cd TDengine
+```
+
+Go 连接器和 Grafana 插件在其他独立仓库，如果安装它们的话，需要在 TDengine 目录下通过此命令安装：
+
+```bash
+git submodule update --init --recursive
+```
+
+## 生成 TDengine
+
+### Linux 系统
+
+```bash
+mkdir debug && cd debug
+cmake .. && cmake --build .
+```
+
+在X86-64、X86、arm64 和 arm32 平台上，TDengine 生成脚本可以自动检测机器架构。也可以手动配置 CPUTYPE 参数来指定 CPU 类型，如 aarch64 或 aarch32 等。
+
+aarch64：
+
+```bash
+cmake .. -DCPUTYPE=aarch64 && cmake --build .
+```
+
+aarch32：
+
+```bash
+cmake .. -DCPUTYPE=aarch32 && cmake --build .
+```
+
+### Windows 系统
+
+如果你使用的是 Visual Studio 2013 版本：
+
+打开 cmd.exe，执行 vcvarsall.bat 时，为 64 位操作系统指定“x86_amd64”，为 32 位操作系统指定“x86”。
+
+```bash
+mkdir debug && cd debug
+"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" < x86_amd64 | x86 >
+cmake .. -G "NMake Makefiles"
+nmake
+```
+
+如果你使用的是 Visual Studio 2019 或 2017 版本：
+
+打开cmd.exe，执行 vcvarsall.bat 时，为 64 位操作系统指定“x64”，为 32 位操作系统指定“x86”。
+
+```bash
+mkdir debug && cd debug
+"c:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" < x64 | x86 >
+cmake .. -G "NMake Makefiles"
+nmake
+```
+
+你也可以从开始菜单中找到"Visual Studio < 2019 | 2017 >"菜单项，根据你的系统选择"x64 Native Tools Command Prompt for VS < 2019 | 2017 >"或"x86 Native Tools Command Prompt for VS < 2019 | 2017 >"，打开命令行窗口，执行：
+
+```bash
+mkdir debug && cd debug
+cmake .. -G "NMake Makefiles"
+nmake
+```
+
+### Mac OS X 系统
+
+安装 Xcode 命令行工具和 cmake. 在 Catalina 和 Big Sur 操作系统上，需要安装 XCode 11.4+ 版本。
+
+```bash
+mkdir debug && cd debug
+cmake .. && cmake --build .
+```
+
+# 安装
+
+如果你不想安装，可以直接在shell中运行。生成完成后，安装 TDengine：
+```bash
+make install
+```
+
+用户可以在[文件目录结构](https://www.taosdata.com/cn/documentation/administrator#directories)中了解更多在操作系统中生成的目录或文件。
+
+安装成功后，在终端中启动 TDengine 服务：
+
+```bash
+taosd
+```
+
+用户可以使用 TDengine Shell 来连接 TDengine 服务，在终端中，输入：
+
+```bash
+taos
+```
+
+如果 TDengine Shell 连接服务成功，将会打印出欢迎消息和版本信息。如果失败，则会打印出错误消息。
+
+## 快速运行
+
+TDengine 生成后，在终端执行以下命令：
+
+```bash
+./build/bin/taosd -c test/cfg
+```
+
+在另一个终端，使用 TDengine shell 连接服务器：
+
+```bash
+./build/bin/taos -c test/cfg
+```
+
+"-c test/cfg"指定系统配置文件所在目录。
+
+# 体验 TDengine
+
+在TDengine终端中，用户可以通过SQL命令来创建/删除数据库、表等，并进行插入查询操作。
+
+```bash
+create database demo;
+use demo;
+create table t (ts timestamp, speed int);
+insert into t values ('2019-07-15 00:00:00', 10);
+insert into t values ('2019-07-15 01:00:00', 20);
+select * from t;
+          ts          |   speed   |
+===================================
+ 19-07-15 00:00:00.000|         10|
+ 19-07-15 01:00:00.000|         20|
+Query OK, 2 row(s) in set (0.001700s)
+```
+
