 As noted in the Beta announcement, React Compiler is compatible with React 17 and up. If you are not yet on React 19, you can use React Compiler by specifying a minimum target in your compiler config, and adding `react-compiler-runtime` as a dependency. You can find docs on this [here](https://react.dev/learn/react-compiler#using-react-compiler-with-react-17-or-18).

 ## What should I do about useMemo, useCallback, and React.memo? {/*what-should-i-do-about-usememo-usecallback-and-reactmemo*/}
 
-If you are using React Compiler, [`useMemo`](/reference/react/useMemo), [`useCallback`](/reference/react/useCallback), and [`React.memo`](/reference/react/memo) can be removed. React Compiler adds automatic memoization more precisely and granularly than is possible with these hooks. If you choose to keep manual memoization, React Compiler will analyze them and determine if your manual memoization matches its automatically inferred memoization. If there isn't a match, the compiler will choose to bail out of optimizing that component.
+React Compiler adds automatic memoization more precisely and granularly than is possible with [`useMemo`](/reference/react/useMemo), [`useCallback`](/reference/react/useCallback), and [`React.memo`](/reference/react/memo). If you choose to keep manual memoization, React Compiler will analyze them and determine if your manual memoization matches its automatically inferred memoization. If there isn't a match, the compiler will choose to bail out of optimizing that component.
 
 This is done out of caution as a common anti-pattern with manual memoization is using it for correctness.  This means your app depends on specific values being memoized to work properly. For example, in order to prevent an infinite loop, you may have memoized some values to stop a `useEffect` call from firing. This breaks the Rules of React, but since it can potentially be dangerous for the compiler to automatically remove manual memoization, the compiler will just bail out instead. You should manually remove your handwritten memoization and verify that your app still works as expected.
