-# V2Ray 用户支持 (User Support)
-
-**English reader please skip to the [English section](#way-to-get-support) below**
-
-## 获得帮助信息的途径
-
-您可以从以下渠道获取帮助：
-
-1. 官方网站：[v2ray.com](https://www.v2ray.com)
-1. Github：[Issues](https://github.com/v2ray/v2ray-core/issues)
-1. Telegram：[主群](https://t.me/projectv2ray)
-
-## Github Issue 规则
-
-1. 请按模板填写 issue；
-1. 配置文件内容使用格式化代码段进行修饰（见下面的解释）；
-1. 在提交 issue 前尝试减化配置文件，比如删除不必要 inbound / outbound 模块；
-1. 在提交 issue 前尝试确定问题所在，比如将 socks 代理换成 http 再次观察问题是否能重现；
-1. 配置文件必须结构完整，即除了必要的隐私信息之外，配置文件可以直接拿来运行。
-
-**不按模板填写的 issue 将直接被关闭**
-
-## 格式化代码段
-
-在配置文件上下加入 Markdown 特定的修饰符，如下：
-
-\`\`\`javascript
-
-{
-  // 配置文件内容
-}
-
-\`\`\`
-
-## Way to Get Support
-
-You may get help in the following ways:
-
-1. Office Site: [v2ray.com](https://www.v2ray.com)
-1. Github: [Issues](https://github.com/v2ray/v2ray-core/issues)
-1. Telegram: [Main Group](https://t.me/projectv2ray)
-
-## Github Issue Rules
-
-1. Please fill in the issue template.
-1. Decorate config file with Markdown formatter (See below).
-1. Try to simplify config file before submitting the issue, such as removing unnecessary inbound / outbound blocks.
-1. Try to determine the cause of the issue, for example, replacing socks inbound with http inbound to see if the issue still exists.
-1. Config file must be structurally complete.
-
-**Any issue not following the issue template will be closed immediately.**
-
-## Code formatter
-
-Add the following Markdown decorator to config file content:
-
-\`\`\`javascript
-
-{
-  // config file
-}
-
-\`\`\`
