+
+Jest's expect matchers as a Chai plugin.
+
+## Usage
+
+```js
+import * as chai from 'chai'
+import { JestAsymmetricMatchers, JestChaiExpect, JestExtend } from '@vitest/expect'
+
+// allows using expect.extend instead of chai.use to extend plugins
+chai.use(JestExtend)
+// adds all jest matchers to expect
+chai.use(JestChaiExpect)
+// adds asymmetric matchers like stringContaining, objectContaining
+chai.use(JestAsymmetricMatchers)
+```
