 The switch component consists of three main parts:
 
-- **Label** (optional): text that describes what the switch controls
-- **Track**: the pill-shaped background that indicates the current state
-- **Thumb**: the circular knob that moves between positions

+- **Track**: the pill-shaped background.
+- **Thumb**: the knob that moves between positions.

+## Basic usage
+
+```clj
+[:> switch* {:label "Toggle something"
+             :default-checked nil
+             :on-change handle-change
+             :disabled false}]
+```
 
 ## Accesibility
 
-When no visible label is provided, use `aria-label` for accessibility.

-## Variants
-
-### With Label
-
-```clj
-[:> switch* {:label "Toggle dark mode"
-             :default-checked false}]
-```
-
-<Canvas of={Switch.WithLabel} />
+When no visible label is provided, use `:aria-label` for accessibility.
 
 ## Usage Guidelines
 
 ### When to Use
 
-- For binary settings that take effect immediately
-- In preference panels and configuration screens
+- For boolean settings that take effect immediately.
+- In preference panels and configuration screens.
+- For ternary states where the third state is only relevant at the beginning (e.g., selection of multiple elements with opposite states).
 
 ### When Not to Use
 
-- For actions that require confirmation (use buttons instead)
-- For multiple choice selections (use radio buttons or select)
-- For temporary states that need explicit "Apply" action
+- For actions that require confirmation (use buttons instead).
+- For multiple choice selections (use radio buttons or select).
+- For temporary states that need explicit "Apply" action.
+- For ternary states that require passing through all three states.
