+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[the Discord server](https://discord.gg/T5vZU6UyeG).
+All complaints will be reviewed and investigated promptly and fairly.
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

 ### Bonus
-When you want to teleport to somewhere, use the ingame marking function on Map, click Confirm. You will see your character falling from a very high destination, exact location that you marked.

 # Quick Troubleshooting
-* If compiling wasn't successful, please check your JDK installation (must be JDK 8 and validated JDK's bin PATH variable)
-* My client doesn't connect, doesn't login, 4206, etc... - Mostly your proxy daemon setup is *the issue*, if using Fiddler make sure it running on another port except 8888

+## 快速设置指南
+
+**附:** 加入我们的 [Discord](https://discord.gg/T5vZU6UyeG) 获取更多帮助！
+
+### 环境需求
+
+* Java SE - 16 (当您没有Oracle账户，可以使用[镜像](https://github.com/adoptium/temurin16-binaries/releases/tag/jdk-16.0.2+7))
+
+  **注:** 如果您仅仅想要简单地**运行服务端**, 那么使用 **jre** 便足够了 
+
+* MongoDB (推荐 4.0+)
+
+* Proxy daemon: mitmproxy (推荐使用mitmdump), Fiddler Classic, 等
+
+### 运行
+
+**注:** 如果您从旧版本升级到新版本，最好删除 `config.json` 并启动服务端jar来重新生成它
+
+1. 获取 `grasscutter.jar`
+   - 从 [actions](https://nightly.link/Grasscutters/Grasscutter/workflows/build/stable/Grasscutter.zip) 中下载
+   - [自行构建](#构建)
+2. 在**grasscutter.jar** 所在目录中创建 `resources` 文件夹并将 `BinOutput` 和 `ExcelBinOutput` 放入其中 *(查看 [wiki](https://github.com/Grasscutters/Grasscutter/wiki) 了解更多)*
+3. 通过命令 `java -jar grasscutter.jar` 来运行Grasscutter. **在此之前请确认MongoDB服务运行正常**
+
+### 连接
+
+½. 在服务器控制台中 [创建账户](#命令列表).
+
+1. 重定向流量: (选其一)
+    - mitmdump:  `mitmdump -s proxy.py -k`
+    
+      信任 CA 证书:
+    
+      ​	**注:** mitmproxy的CA证书通常存放在 `% USERPROFILE%\ .mitmproxy`, 或者你也可以从`http://mitm.it` 中下载它
+    
+      ​	双击来[安装根证书](https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate#installing-a-trusted-root-certificate) 或者..
+    
+      - 使用命令行
+    
+        ```shell
+        certutil -addstore root %USERPROFILE%\.mitmproxy\mitmproxy-ca-cert.cer
+        ```
+    
+    - Fiddler Classic: 运行Fiddler Classic, 在设置中开启 `解密https通信` 并将端口切换到除`8888` 以外的任意端口 (工具 -> 选项 -> 连接) 并加载 [此脚本](https://github.lunatic.moe/fiddlerscript).
+      
+    - [Hosts文件](https://github.com/Grasscutters/Grasscutter/wiki/Running#traffic-route-map)
+    
+2. 设置代理为 `127.0.0.1:8080` 或其它你所设定的端口
+
+**你也可以简单地运行 `start.cmd` 来全自动启动服务端并设置代理**
+
+### 构建
+
+Grasscutter 使用 Gradle 来处理依赖及构建.
+
+**依赖:**
+
+- Java SE Development Kits - 16
+- Git
+
+##### Windows
+
+```shell
+git clone https://github.com/Grasscutters/Grasscutter.git
+cd Grasscutter
+.\gradlew.bat # Setting up environments
+.\gradlew jar # Compile
+```
+
+##### Linux
+
+```bash
+git clone https://github.com/Grasscutters/Grasscutter.git
+cd Grasscutter
+chmod +x gradlew
+./gradlew jar # Compile
+```
+
+你可以在项目根目录中找到`grasscutter.jar`
+
+## 命令列表
+
+你可能需要在终端中运行 `java -jar grasscutter.jar -handbook` 它将会创建一个 `GM Handbook.txt` 以方便您查阅物品ID等
+
+在每个玩家的朋友列表中都有一个名为“服务器”的虚拟用户，你可以通过发送消息来使用命令。命令也适用于其他聊天室，例如私人/团队聊天。
+要在游戏中使用命令，需要添加 `/` 或 `!` 前缀，如 `/pos`
