-# V2Ray 内核
-
-V2Ray 内核可以单独使用，也可以配置其它程序一起使用。
-
-官网：https://www.v2ray.com/
-
-## 使用方式
-
-### Windows 或 macOS
-
-压缩包内的 config.json 是默认的配置文件，无需修改即可使用。配置文件的详细信息可以在官网找到。
-
-* Windows 中的可执行文件为 v2ray.exe 和 wv2ray.exe。双击即可运行。
-  * v2ray.exe 是一个命令行程序，启动后可以看到命令行界面。
-  * wv2ray.exe 是一个后台程序，没有界面，会在后台自动运行。
-* macOS 中的可执行文件为 v2ray。右键单击，然后选择使用 Terminal 打开即可。
-
-### Linux
-
-压缩包中包含多个配置文件，按需使用。
-
-可执行程序为 v2ray，启动命令：
-
-```bash
-v2ray --config=<full path>
-```
-
-## 验证文件
-
-压缩包中的 .sig 文件为 GPG 签名文件，用来验证对应程序文件的真实性。签名公钥可以在下面的链接找到：
-
-https://github.com/v2ray/v2ray-core/blob/master/release/verify/official_release.asc
-
-## 问题反馈
-
-* Github: https://github.com/v2ray/v2ray-core
