+## Spinner
+
+A spinner, useful for indicating that some kind of invisible operation is
+happening. There are a couple default ones, but you can also pass your own
+”frames.”
+
+## Text Input
+
+A text input field, akin to an `<input type="text">` in HTML.
+
+## Paginator
+
+A component for handling pagination logic and optionally drawing pagination UI.
+
+## Viewport
+
+A viewport for vertically scrolling content which optionally includes standard
+pager keybindings and mouse wheel support. A high performance mode is available
+for applications which make use of the alterate screen buffer. This is
+generally only necessary when dealing with content with a very large amount of
+ANSI escape sequences.
