 This feature only **simulates** the fingerprint of `TLS Client Hello` message, leaving other behaviours the same as vanilla Go TLS. If you want to simulate a browser `TLS` more completely, use the [Browser Dialer](./transports/websocket.md#browser-dialer).

+::: tip
+When using this feature, some TLS options that affect the TLS fingerprint will be overridden by the utls library and will no longer be effective, such as ALPN.
+The parameters that will be passed are

 > `pinnedPeerCertificateChainSha256`: [string]
 
 Specifies the SHA256 hash values of the certificate chain of the remote server, using the standard encoding format. Only when the hash value of the server-side certificate chain matches any of the specified can a TLS connection be successfully established.

 ### 5.2 基于 IP 文件分流：`geoip.dat`
 
-与 `geosite.dat` 规则文件十分类似的，我们还有 `geoip.dat` 这个规则文件，它致力于为用户提供成熟完善的【IP 分类表】。让用户可以简单的通过 `geoip:xxx` 这种格式方便的调用任何子类，定制符合自身需求的路由规则 。
+除了使用 `geosite.dat` 核心自然也支持直接使用IP进行路由以满足各种需求。
