 A library for working with timers, timeouts, and intervals with the `futures`
 crate.
 
-```toml
-# Cargo.toml
-[dependencies]
-futures-timer = "0.3"
-```
-
-An example of using a `Delay` is:
-
-```rust
-use std::time::Duration;
-
-use futures::prelude::*;
-use futures_timer::Delay;
-
-async fn main() -> Result<(), Box<dyn Error + Send + Sync + 'static>> {
-    Delay::new(Duration::from_secs(3))
-        .map(|()| println!("printed after three seconds"))
-        .await?;
-}
-```
-
-And using an `Interval`:
-
-```rust
-use std::time::Duration;
-
-use futures::prelude::*;
-use futures_timer::Interval;
-
-#[runtime::main]
-async fn main() -> Result<(), Box<dyn Error + Send + Sync + 'static>> {
-    Interval::new(Duration::from_secs(4))
-        .take(4)
-        .for_each(|()| Ok(println!("printed after three seconds")))
-        .await?;
-}
-```
-
-Or timing out a future
-
-```rust
-use std::time::Duration;
-
-use futures_timer::FutureExt;
-
-async fn main() -> Result<(), Box<dyn Error + Send + Sync + 'static>> {
-    // create a future that will take at most 3 seconds to resolve
-    let future = long_running_future()
-      .timeout(Duration::from_secs(3));
-}
-```
