 //! Types for creating animations.
+//!
+//! Animations in Gooey are performed by transitioning a [`Dynamic`]'s contained
+//! value over time. This starts with [`Dynamic::transition_to()`], which
+//! returns a [`DynamicTransition`].
+//!
+//! [`DynamicTransition`] implements [`AnimationTarget`], a trait that describes
+//! types that can be updated using [linear interpolation](LinearInterpolate).
+//! `AnimationTarget` is also implemented for tuples of `AnimationTarget`
+//! implementors, allowing multiple transitions to be an `AnimationTarget`.
+//!
+//! Next, the [`AnimationTarget`] is turned into an animation by invoking
+//! [`AnimationTarget::over()`] with the [`Duration`] the transition should
+//! occur over. The animation can further be customized using
+//! [`Animation::with_easing()`] to utilize any [`Easing`] implementor.
+//!
+//! ```rust
+//! use std::time::Duration;
+//!
+//! use gooey::animation::{AnimationTarget, Spawn};
+//! use gooey::value::Dynamic;
+//!
+//! let value = Dynamic::new(0);
+//!
+//! value
+//!     .transition_to(100)
+//!     .over(Duration::from_millis(100))
+//!     .launch();
+//!
+//! let mut reader = value.into_reader();
+//! while reader.block_until_updated() {
+//!     println!("{}", reader.get());
+//! }
+//!
+//! assert_eq!(reader.get(), 100);
