+# 贡献指南
+
+我们感谢所有开发者提交贡献。随时关注我们，Fork 存储库，报告错误，以及在 GitHub 上提交您的代码。但是，我们希望开发者遵循我们的指南，才能更好的做出贡献。
+
+## 报告错误
+
+- 任何用户都可以通过 **[GitHub issue tracker](https://github.com/taosdata/TDengine/issues)** 向我们报告错误。请您对所遇到的问题进行**详细描述**，最好提供重现错误的详细步骤。
+- 欢迎提供包含由 Bug 生成的日志文件的附录。
+
+## 需要强调的代码提交规则
+
+- 在提交代码之前，需要**同意贡献者许可协议（CLA）**。点击 [TaosData CLA](https://cla-assistant.io/taosdata/TDengine) 阅读并签署协议。如果您不接受该协议，请停止提交。
+- 请在 [GitHub issue tracker](https://github.com/taosdata/TDengine/issues) 中解决问题或添加注册功能。
+- 如果在 [GitHub issue tracker](https://github.com/taosdata/TDengine/issues) 中没有找到相应的问题或功能，请**创建一个新的 issue**。
+- 将代码提交到我们的存储库时，请创建**包含问题编号的 PR**。
+
+## 贡献指南
+
+1. 请用友好的语气书写。
+
+2. **主动语态**总体上优于被动语态。主动语态中的句子会突出执行动作的人，而不是被动语态突出动作的接受者。
+
+3. 文档写作建议
+
+- 正确拼写产品名称 “TDengine”。 “TD” 用大写字母，“TD” 和 “engine” 之间没有空格 **（正确拼写：TDengine）**。
+- 在句号或其他标点符号后只留一个空格。
+
+4. 尽量**使用简单句**，而不是复杂句。
+
+## 给贡献者的礼品
+
+只要您是为 TDengine 做贡献的开发者，不管是代码贡献、修复 bug 或功能请求，还是文档更改，您都将会获得一份**特别的贡献者纪念品礼物**！

 Interface functions return a value that indicates whether the operation was successful. If an operation fails, the interface function returns an error code. Otherwise, it returns TSDB_CODE_SUCCESS. The error codes are defined in `taoserror.h` and in the common API error codes in `taos.h`. For example, TSDB_CODE_UDF_INVALID_INPUT indicates invalid input. TSDB_CODE_OUT_OF_MEMORY indicates insufficient memory.

 TDengine SQL is the major interface for users to write data into or query from TDengine. It uses standard SQL syntax and includes extensions and optimizations for time-series data and services. The maximum length of a TDengine SQL statement is 1 MB. Note that keyword abbreviations are not supported. For example, DELETE cannot be entered as DEL.

-taosAdapter has been part of TDengine server software since TDengine v2.4.0.0. If you use the TDengine server, you don't need additional steps to install taosAdapter. You can download taosAdapter from [TDengine official website](https://tdengine.com/all-downloads/) to download the TDengine server installation package (taosAdapter is included in v2.4.0.0 and later version). If you need to deploy taosAdapter separately on another server other than the TDengine server, you should install the full TDengine server package on that server to install taosAdapter. If you need to build taosAdapter from source code, you can refer to the [Building taosAdapter]( https://github.com/taosdata/taosadapter/blob/3.0/BUILD.md) documentation.

-sidebar_label: TDengine in Docker
-title: Deploy TDengine in Docker
----
-
-We do not recommend deploying TDengine using Docker in a production system. However, Docker is still very useful in a development environment, especially when your host is not Linux. From version 2.0.14.0, the official image of TDengine can support X86-64, X86, arm64, and rm32 .
-
-In this chapter we introduce a simple step by step guide to use TDengine in Docker.
-
-## Install Docker
-
-To install Docker please refer to [Get Docker](https://docs.docker.com/get-docker/).
-
-After Docker is installed, you can check whether Docker is installed properly by displaying Docker version.
-
-```bash
-$ docker -v
-Docker version 20.10.3, build 48d30b5
-```
-
-## Launch TDengine in Docker
-
-### Launch TDengine Server
-
-```bash
-$ docker run -d -p 6030-6049:6030-6049 -p 6030-6049:6030-6049/udp tdengine/tdengine
-526aa188da767ae94b244226a2b2eec2b5f17dd8eff592893d9ec0cd0f3a1ccd
-```
-
-In the above command, a docker container is started to run TDengine server, the port range 6030-6049 of the container is mapped to host port range 6030-6049. If port range 6030-6049 has been occupied on the host, please change to an available host port range. For port requirements on the host, please refer to [Port Configuration](/reference/config/#serverport).
-
-- **docker run**: Launch a docker container
-- **-d**: the container will run in background mode
-- **-p**: port mapping
-- **tdengine/tdengine**: The image from which to launch the container
-- **526aa188da767ae94b244226a2b2eec2b5f17dd8eff592893d9ec0cd0f3a1ccd**: the container ID if successfully launched.
-
-Furthermore, `--name` can be used with `docker run` to specify name for the container, `--hostname` can be used to specify hostname for the container, `-v` can be used to mount local volumes to the container so that the data generated inside the container can be persisted to disk on the host.
-
-```bash
-docker run -d --name tdengine --hostname="tdengine-server" -v ~/work/taos/log:/var/log/taos -v ~/work/taos/data:/var/lib/taos  -p 6030-6049:6030-6049 -p 6030-6049:6030-6049/udp tdengine/tdengine
-```
-
-- **--name tdengine**: specify the name of the container, the name can be used to specify the container later
-- **--hostname=tdengine-server**: specify the hostname inside the container, the hostname can be used inside the container without worrying the container IP may vary
-- **-v**: volume mapping between host and container
-
-### Check the container
-
-```bash
-docker ps
-```
-
-The output is like below:
-
-```
-CONTAINER ID   IMAGE               COMMAND   CREATED          STATUS          ···

-```
-
-- **docker ps**: List all the containers
-- **CONTAINER ID**: Container ID
-- **IMAGE**: The image used for the container
-- **COMMAND**: The command used when launching the container
-- **CREATED**: When the container was created
-- **STATUS**: Status of the container
-
-### Access TDengine inside container
-
-```bash
-$ docker exec -it tdengine /bin/bash
-root@tdengine-server:~/TDengine-server-2.4.0.4#
-```
-
-- **docker exec**: Attach to the container
-- **-i**: Interactive mode
-- **-t**: Use terminal
-- **tdengine**: Container name, up to the output of `docker ps`
-- **/bin/bash**: The command to execute once the container is attached
-
-Inside the container, start TDengine CLI `taos`
-
-```bash
-root@tdengine-server:~/TDengine-server-2.4.0.4# taos
-

-
-taos>
-```
-
-The above example is for a successful connection. If `taos` fails to connect to the server side, error information would be shown.
-
-In TDengine CLI, SQL commands can be executed to create/drop databases, tables, STables, and insert or query data. For details please refer to [TAOS SQL](/taos-sql/).
-
-### Access TDengine from host
-
-If option `-p` used to map ports properly between host and container, it's also able to access TDengine in container from the host as long as `firstEp` is configured correctly for the client on host.

-
-### Run TDengine server and taosAdapter inside container
-
-From version 2.4.0.0, in the TDengine Docker image, `taosAdapter` is enabled by default, but can be disabled using environment variable `TAOS_DISABLE_ADAPTER=true` . `taosAdapter` can also be run alone without `taosd` when launching a container.
-
-For the port mapping of `taosAdapter`, please refer to [taosAdapter](/reference/taosadapter/).
-
-- Run both `taosd` and `taosAdapter` (by default) in docker container:
-
-```bash
-docker run -d --name tdengine-all -p 6030-6049:6030-6049 -p 6030-6049:6030-6049/udp tdengine/tdengine:2.4.0.4
-```
-
-- Run `taosAdapter` only in docker container, `TAOS_FIRST_EP` environment variable needs to be used to specify the container name in which `taosd` is running:
-
-```bash
-docker run -d --name tdengine-taosa -p 6041-6049:6041-6049 -p 6041-6049:6041-6049/udp -e TAOS_FIRST_EP=tdengine-all tdengine/tdengine:2.4.0.4 taosadapter
-```
-
-- Run `taosd` only in docker container:
-
-```bash
-docker run -d --name tdengine-taosd -p 6030-6042:6030-6042 -p 6030-6042:6030-6042/udp -e TAOS_DISABLE_ADAPTER=true tdengine/tdengine:2.4.0.4

-### Access TDengine from 3rd party tools
-
-A lot of 3rd party tools can be used to write data into TDengine through `taosAdapter`, for details please refer to [3rd party tools](/third-party/).
-
-There is nothing different from the 3rd party side to access TDengine server inside a container, as long as the end point is specified correctly, the end point should be the FQDN and the mapped port of the host.
-
-## Stop TDengine inside container
-
-```bash
-docker stop tdengine
-```
-
-- **docker stop**: stop a container
-- **tdengine**: container name

 ### 17. 为什么 RESTful 接口无响应、Grafana 无法添加 TDengine 为数据源、TDengineGUI 选了 6041 端口还是无法连接成功？
 
-taosAdapter 从 TDengine 2.4.0.0 版本开始成为 TDengine 服务端软件的组成部分，是 TDengine 集群和应用程序之间的桥梁和适配器。在此之前 RESTful 接口等功能是由 taosd 内置的 HTTP 服务提供的，而如今要实现上述功能需要执行：```systemctl start taosadapter``` 命令来启动 taosAdapter 服务。
+这个现象可能是因为 taosAdapter 没有被正确启动引起的，需要执行：```systemctl start taosadapter``` 命令来启动 taosAdapter 服务。
 
 需要说明的是，taosAdapter 的日志路径 path 需要单独配置，默认路径是 /var/log/taos ；日志等级 logLevel 有 8 个等级，默认等级是 info ，配置成 panic 可关闭日志输出。请注意操作系统 / 目录的空间大小，可通过命令行参数、环境变量或配置文件来修改配置，默认配置文件是 /etc/taos/taosadapter.toml 。
