 ## Usage
 
-[Examples](./examples) require environment variables `BANCHO_USERNAME` and `BANCHO_PASSWORD` at **compile time**, specify them like below:
-
-```bash
-BANCHO_USERNAME=username BANCHO_PASSWORD=password cargo run --example echobot
-```
-
-This is a minimal echo bot example. See more [examples](./examples).
-
-```rust
-use closur::bancho::{Client, ClientOptions, Event};
-
-type Result<T> = std::result::Result<T, Box<dyn std::error::Error + Send + Sync>>;
-
-// This example shows how to create a simple echo bot.
-#[tokio::main]
-async fn main() -> Result<()> {
-    // "BANCHO_USERNAME" and "BANCHO_PASSWORD" are **compile-time** environment variables.
-    // You need to set username and password, e.g. running
-    // `BANCHO_USERNAME=username BANCHO_PASSWORD=password cargo run --example echobot`
-    let options = ClientOptions::default()
-        .username(env!("BANCHO_USERNAME").to_string())
-        .password(env!("BANCHO_PASSWORD").to_string());
-
-    let mut client = Client::new(options).await?;
-    let mut writer = client.writer();
-    client.auth().await?;
-
-    println!("[ECHOBOT] Connected and authenticated, waiting for events...");
-    let mut subscriber = client.events();
-    loop {
-        let event = subscriber.recv().await?;
-        match event {
-            Event::Message { from, body, .. } => {
-                println!("[PM] {}: {}", from.to_string(), body);
-                if body.starts_with("!echo") {
-                    let message = body.trim_start_matches("!echo").trim();
-                    println!("[EVENT] Sent echo message to {}: {}", from, message);
-                    writer.send_private_chat(from, message).await?;
-                }
