-# Fourth
-
-> 这一波在第四层。

-
-[English](/README-EN.md)
-
-**积极开发中，0.1版本迭代可能较快**
-
-Fourth是一个Rust实现的Layer 4代理，用于监听指定端口TCP/KCP流量，并根据规则转发到指定目标（目前只支持TCP）。
-
-## 功能
-
-- 监听指定端口代理到本地或远端指定端口
-- 监听指定端口，通过TLS ClientHello消息中的SNI进行分流
-- 支持KCP入站（警告：未测试）
-
-## 安装方法
-
-为了确保获得您架构下的最佳性能，请考虑自行编译，首选需要确保您拥有[Rust工具链](https://rustup.rs/)。
-
-```bash
-$ cd fourth
-$ cargo build --release
-```
-
-将在`target/release/fourth`生成二进制文件，您也可以使用`cargo install --path . `来安装二进制文件。
-
-或者您也可以使用Cargo直接安装：
-
-```bash
-$ cargo install fourth
-```
-
-或者您也可以直接从Release中下载二进制文件。
-
-## 配置
-
-Fourth使用yaml格式的配置文件，默认情况下会读取`/etc/fourth/config.yaml`，您也可以设置自定义路径到环境变量`FOURTH_CONFIG`，如下是一个最小有效配置：
-
-```yaml
-version: 1
-log: info
-
-servers:
-  proxy_server:
-    listen:
-      - "127.0.0.1:8081"
-    default: remote
-
-upstream:
-  remote: "tcp://www.remote.example.com:8082" # proxy to remote address
-```
-
-内置两个的upstream：ban（立即中断连接）、echo（返回读到的数据）。更详细的配置可以参考[示例配置](./example-config.yaml)。
-
-注意：[::]会默认同时绑定IPv4和IPv6。
-
-## 性能测试
-
-在4C2G的服务器上测试：
-
-使用Fourth代理到Nginx（直连QPS 120000）: ~70000req/s （测试命令：`wrk -t200 -c1000 -d120s --latency http://proxy-server:8081 `）
-
-使用Fourth代理到本地iperf3：8Gbps
-
-## io_uring?
-
-尽管经过了很多尝试，我们发现目前一些Rust下面的io_uring实现存在问题，我们使用的io_uring库实现尽管在吞吐量上可以做到单线程20Gbps（相比之下Tokio仅有8Gbps），但在QPS上存在性能损失较大的问题。因此在有成熟的io_uring实现之前，我们仍然选择epoll。之后我们会持续关注相关进展。
-
-可能以后会为Linux高内核版本的用户提供可选的io_uring加速。

-Fourth is a layer 4 proxy implemented by Rust to listen on specific ports and transfer TCP/KCP data to remote addresses(only TCP) according to configuration.
+`l4p` is a layer 4 proxy implemented by Rust to listen on specific ports and transfer TCP/KCP data to remote addresses(only TCP) according to configuration.
 
 ## Features
 
 - Listen on specific port and proxy to local or remote port
 - SNI-based rule without terminating TLS connection
-- Allow KCP inbound(warning: untested)
+- DNS-based backend with periodic resolution
 
 ## Installation
 
 To gain best performance on your computer's architecture, please consider build the source code. First, you may need [Rust tool chain](https://rustup.rs/).
 
 ```bash
-$ cd fourth
+$ cd l4p
 $ cargo build --release
 ```
 
-Binary file will be generated at `target/release/fourth`, or you can use `cargo install --path .` to install.

+Or you can use Cargo to install `l4p`:

-$ cargo install fourth
+$ cargo install l4p
 ```
 
 Or you can download binary file form the Release page.
 
 ## Configuration
 
-Fourth will read yaml format configuration file from `/etc/fourth/config.yaml`, and you can set custom path to environment variable `FOURTH_CONFIG`, here is an minimal viable example:
