+//! While [`current_thread::Runtime`][rt] does not implement `Send` and cannot
+//! safely be moved to other threads, it provides a `Handle` that can be sent
+//! to other threads and allows to spawn new tasks from there.
+//!
+//! For example:
+//!
+//! ```
+//! # extern crate tokio;
+//! # extern crate futures;
+//! use tokio::runtime::current_thread::Runtime;
+//! use tokio::prelude::*;
+//! use std::thread;
+//!
+//! # fn main() {
+//! let mut runtime = Runtime::new().unwrap();
+//! let handle = runtime.handle();
+//!
+//! thread::spawn(move || {
+//!     handle.spawn(future::ok(()));
+//! }).join().unwrap();
+//!
+//! # /*
+//! runtime.run().unwrap();
+//! # */
+//! # }
+//! ```
+//!
+//! # Examples
+//!
+//! Creating a new `Runtime` and running a future `f` until its completion and
+//! returning its result.
+//!
+//! ```
+//! use tokio::runtime::current_thread::Runtime;
+//! use tokio::prelude::*;
+//!
+//! let mut runtime = Runtime::new().unwrap();
+//!
+//! // Use the runtime...
+//! // runtime.block_on(f); // where f is a future
+//! ```

 # Changes
 
-## Unreleased - 2020-xx-xx
-
-
-## 1.0.6 - 2020-08-09
-
-### Fixed
-
-* Removed unsound custom Cell implementation that allowed obtaining several mutable references to the same data, which is undefined behavior in Rust and could lead to violations of memory safety. External code could obtain several mutable references to the same data through service combinators. Attempts to acquire several mutable references to the same data will instead result in a panic.
