 Fastcgi client implemented for Rust.
 
-## Example
+## Features
 
-```rust
+Support both `async(async-std)` and `sync(std)` clients.
+
+Be default, both `async` and `sync` client are included, if you don't want to include `async` client,
+You can specify `default-features = false` in `Cargo.toml`.
+
+## Installation
+
+With [cargo add](https://github.com/killercup/cargo-edit) installed run:
+
+```bash
+$ cargo add fastcgi-client
+```
+
+## Examples
+
+Async `async-std` client:
+
+```
+use fastcgi_client::{AsyncClient, Params};
+use std::env;
+use async_std::{io, task};
+use async_std::net::TcpStream;

+
+    // Connect to php-fpm default listening address.
+    let stream = TcpStream::connect(("127.0.0.1", 9000)).await.unwrap();
+    let mut client = AsyncClient::new(stream, false);
