 To use Vitest with TypeScript, create a file named `jest-extended.d.ts` with the content below in addition to the setup above.
 
+#### Vitest >= 0.31.0
+
 ```typescript
-/// <reference types="vitest" />
+import type CustomMatchers from 'jest-extended';
+import 'vitest';
+
+declare module 'vitest' {
+  interface Assertion<T = any> extends CustomMatchers<T> {}
+  interface AsymmetricMatchersContaining<T = any> extends CustomMatchers<T> {}
+  interface ExpectStatic extends CustomMatchers<T> {}
+}
+```
 
-export interface CustomMatchers<R> extends Record<string, any> {
-  toHaveBeenCalledAfter(
-    mock: jest.MockInstance<any, any[]> | import('vitest').MockInstance<any, any[]>,
-    failIfNoFirstInvocation?: boolean,
-  ): R;
+This can be combined with matchers from other dependencies or your own custom matchers. Here's an example of a custom matcher.
 
-  toHaveBeenCalledBefore(
-    mock: jest.MockInstance<any, any[]> | import('vitest').MockInstance<any, any[]>,
-    failIfNoSecondInvocation?: boolean,
-  ): R;
+```typescript
+import type CustomMatchers from 'jest-extended';
+import 'vitest';

-For Vitest >= 0.31.0, append the content below to the new file.
+#### Vitest < 0.31.0
 
 ```typescript

+import type CustomMatchers from 'jest-extended';

+  interface ExpectStatic extends CustomMatchers<T> {}
 }

-For Vitest < 0.31.0, append the content below to the new file.
+This can be combined with matchers from other dependencies or your own custom matchers. Here's an example of a custom matcher.
 
 ```typescript
-declare namespace Vi {
