+//! `bevy_picking::input` is a thin layer that provides unsurprising default inputs to `bevy_picking`.
+//! The included systems are responsible for sending  mouse and touch inputs to their
+//! respective `Pointer`s.
+//!
+//! Because this resides in its own crate, it's easy to omit it, and provide your own inputs as
+//! needed. Because `Pointer`s aren't coupled to the underlying input hardware, you can easily mock
+//! inputs, and allow users full accessibility to map whatever inputs they need to pointer input.
+//!
+//! If, for example, you wanted to add support for VR input, all you need to do is spawn a pointer
+//! entity with a custom [`PointerId`](crate::pointer::PointerId), and write a system
+//! that updates its position.
