 - HTTPS certificate handling is compatible with [mitmproxy](https://mitmproxy.org/) and stored in the `~/.mitmproxy` folder. If the root certificate is already trusted from a previous use of `mitmproxy`, `go-mitmproxy` can use it directly.
 - Map Remote and Map Local support.
 - HTTP/2 support.
+- WebSocket support.
 - Refer to the [configuration documentation](#additional-parameters) for more features.
 
 ## Unsupported features
 
 - Only supports setting the proxy manually in the client, not transparent proxy mode.
-- Currently does not support WebSocket protocol parsing.
 
 > For more information on the difference between manually setting a proxy and transparent proxy mode, please refer to the mitmproxy documentation for the Python version: [How mitmproxy works](https://docs.mitmproxy.org/stable/concepts-howmitmproxyworks/). go-mitmproxy currently supports "Explicit HTTP" and "Explicit HTTPS" as mentioned in the article.

 - HTTPS 证书相关逻辑与 [mitmproxy](https://mitmproxy.org/) 兼容，并保存在 `~/.mitmproxy` 文件夹中。如果之前已经用过 `mitmproxy` 并安装信任了根证书，则 `go-mitmproxy` 可以直接使用。
 - 支持 Map Remote 和 Map Local。
 - 支持 HTTP/2
+- 支持 WebSocket 协议解析。
 - 更多功能请参考[配置文档](#更多参数)。
 
 ## 暂未实现的功能
 
 - 只支持客户端显示设置代理，不支持透明代理模式。
-- 暂不支持 websocket 协议解析。
 
 > 如需了解显示设置代理和透明代理模式的区别，请参考 Python 版本的 mitmproxy 文档：[How mitmproxy works](https://docs.mitmproxy.org/stable/concepts-howmitmproxyworks/)。`go-mitmproxy` 目前支持文中提到的『Explicit HTTP』和『Explicit HTTPS』。
