+# Recommends to use the `next` tooltip instead of the current stable one.
+
+## Rule details
+
+This rule recommends using the tooltip that is imported from `@primer/react/next` instead of the main entrypoint. The components that are exported from `@primer/react/next` are recommended over the main entrypoint ones because `next` components are reviewed and remediated for accessibility issues.
+👎 Examples of **incorrect** code for this rule:
+
+```tsx
+import {Tooltip} from '@primer/react'
+```
+
+👍 Examples of **correct** code for this rule:
+
+```tsx
+import {Tooltip} from '@primer/react/next'
+```
+
+## Icon buttons and tooltips
+
+Even though the below code is perfectly valid, since icon buttons now come with tooltips by default, it is not required to explicitly use the Tooltip component on icon buttons.
+
+```jsx
+import {IconButton} from '@primer/react'
+import {Tooltip} from '@primer/react/next'
+
+function ExampleComponent() {
+  return (
+    <Tooltip text="Search" direction="e">
+      <IconButton icon={SearchIcon} aria-label="Search" />
+    </Tooltip>
+  )
+}
+```
