-## 需要强调的代码提交规则
+## 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**。
+1. 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。
+2. 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**。
+3. 将TDengine仓库库fork到自己的账户中并创建分支(branch)。
+   注意：默认分支`main`不能直接接受PR，请基于开发分支`3.0`创建自己的分支。
+   注意：修改文档的分支要以`docs/`为开头，以免进行不必要的测试。
+4. 创建pull request，将自己的分支合并到开发分支`3.0`，我们开发团队将尽快审核。
 
-## 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。
+如遇任何问题，请添加官方微信TDengineECO。我们的团队会帮忙解决。

+# Contributing to TDengine
 
-We appreciate contributions from all developers. Feel free to follow us, fork the repository, report bugs, and even submit your code on GitHub. However, we would like developers to follow the guidelines in this document to ensure effective cooperation.
+TDengine Community Edition is free, open-source software. Its development is led by the TDengine Team, but we welcome contributions from all community members and open-source developers. This document describes how you can contribute, no matter whether you're a user or a developer yourself.
 
-## Reporting a bug
+## Bug reports
 
-- Any users can report bugs to us through the **[GitHub issue tracker](https://github.com/taosdata/TDengine/issues)**. We would appreciate if you could provide **a detailed description** of the problem you encountered, including steps to reproduce it.
+All users can report bugs to us through the **[GitHub issue tracker](https://github.com/taosdata/TDengine/issues)**. To ensure that the development team can locate and resolve the issue that you experienced, please include the following in your bug report:
 
-- Attaching log files caused by the bug is really appreciated.
+- A detailed description of the issue, including the steps to reproduce it.
+- Any log files that may be relevant to the issue.
 
-## Guidelines for committing code
+## Code contributions
 
-- You must agree to the **Contributor License Agreement(CLA) before submitting your code patch**. Follow the **[TAOSData CLA](https://cla-assistant.io/taosdata/TDengine)** link to read through and sign the agreement. If you do not accept the agreement, your contributions cannot be accepted.
+Developers are encouraged to submit patches to the project, and all contributions, from minor documentation changes to bug fixes, are appreciated by our team. To ensure that your code can be merged successfully and improve the experience for other community members, we ask that you go through the following procedure before submitting a pull request: 
 
-- Please solve an issue or add a feature registered in the **[GitHub issue tracker](https://github.com/taosdata/TDengine/issues)**.
-- If no corresponding issue or feature is found in the issue tracker, please **create one**.
-- When submitting your code to our repository, please create a pull request with the **issue number** included.
+1. Read and accept the terms of the TAOS Data Contributor License Agreement (CLA) located at [https://cla-assistant.io/taosdata/TDengine](https://cla-assistant.io/taosdata/TDengine).
 
-## Guidelines for communicating
+2. For bug fixes, search the [GitHub issue tracker](https://github.com/taosdata/TDengine/issues) to check whether the bug has already been filed.
+   - If the bug that you want to fix already exists in the issue tracker, review the previous discussion before submitting your patch.
+   - If the bug that you want to fix does not exist in the issue tracker, click **New issue** and file a report.
+   - Ensure that you note the issue number in your pull request when you submit your patch.
+	
+3. Fork our repository to your GitHub account and create a branch for your patch.
+   **Important:** The `main` branch is for stable versions and cannot accept patches directly. For all code and documentation changes, create your own branch from the development branch `3.0` and not from `main`.
+   Note: For a documentation change, ensure that the branch name starts with `docs/` so that the change can be merged without running tests.
+   
+4. Create a pull request to merge your changes into the development branch `3.0`, and our team members will review the request as soon as possible.
 
-1. Please be **nice and polite** in the description.
-2. **Active voice is better than passive voice in general**. Sentences in the active voice will highlight who is performing the action rather than the recipient of the action highlighted by the passive voice.
-3. Documentation writing advice
+If you encounter any difficulties or problems in contributing your code, you can join our [Discord server](https://discord.com/invite/VZdSuUg4pS) and receive assistance from members of the TDengine Team.
 
-- Spell the product name "TDengine" correctly. "TD" is written in capital letters, and there is no space between "TD" and "engine" (**Correct spelling: TDengine**).
-- Please **capitalize the first letter** of every sentence.
-- Leave **only one space** after periods or other punctuation marks.
-- Use **American spelling**.
-- When possible, **use second person** rather than first person (e.g.“You are recommended to use a reverse proxy such as Nginx.” rather than “We recommend to use a reverse proxy such as Nginx.”).
+## Expressing our thanks
 
-5. Use **simple sentences**, rather than complex sentences.
