 /**
- * Define a styled Button, using the `useButton` hook.
- * {@docCategory Button}
+ * Buttons give people a way to trigger an action.
+ *
+ * They’re typically found in forms, dialog panels, and dialogs. Some buttons are specialized for particular tasks,
+ * such as navigation, repeated actions, or presenting menus.
+ *
+ * See also:
+ * [MenuButton](/?path=/docs/components-menubutton--menu-button-playground),
+ * [ToggleButton](/?path=/docs/components-togglebutton--toggle-button-playground),
+ * [CompoundButton](/?path=/docs/components-compoundbutton--compound-button-playground)
+ *
+ * ## Best practices
+ * ### Layout
+ * - For dialog boxes and panels, where people are moving through a sequence of screens, right-align buttons with the
+ * container.
+ * - For single-page forms and focused tasks, left-align buttons with the container.
+ * - Always place the primary button on the left, the secondary button just to the right of it.
+ * - Show only one primary button that inherits theme color at rest state. If there are more than two buttons with
+ * equal priority, all buttons should have neutral backgrounds.
+ * - Don't use a button to navigate to another place; use a link instead. The exception is in a wizard where "Back" and
+ * "Next" buttons may be used.
+ * - Don't place the default focus on a button that destroys data. Instead, place the default focus on the button that
+ * performs the "safe act" and retains the content (such as "Save") or cancels the action (such as "Cancel").
+ *
+ * ### Content
+ * - Use sentence-style capitalization—only capitalize the first word. For more info, see
+ * [Capitalization](https://docs.microsoft.com/en-us/style-guide/capitalization) in the Microsoft Writing Style Guide.
+ * - Make sure it's clear what will happen when people interact with the button. Be concise; usually a single verb
+ * is best. Include a noun if there is any room for interpretation about what the verb means.
+ * For example, "Delete folder" or "Create account".
