+# Change Context.Provider to Context
+
+## Description
+
+This codemod will remove the usage of `Provider` for contexts; e.g., Context.Provider to Context
+
+## Example
+
+### Before:
+
+```tsx
+function App() {
+  const [theme, setTheme] = useState('light');
+  // ...
+  return (
+    <ThemeContext.Provider value={theme}>
+      <Page />
+    </ThemeContext.Provider>
+  );
+}
+```
+
+### After:
+
+```tsx
+function App() {
+  const [theme, setTheme] = useState('light');
+  // ...
+  return (
+    <ThemeContext value={theme}>
+      <Page />
+    </ThemeContext>
+  );
+}
+```
