-### Typescript does not recognize expect().toBeInTheDocument()
-
-This is likely an issue with newer package managers.
-
-The `@storybook/jest` package provides some type augmentations so that `expect` has extended matchers coming from Testing Library. The way it works, is that `@storybook/jest` depends on `@testing-library/jest-dom`, a package that depends on `@types/testing-library__jest-dom`. That @types package should be hoisted in your project in order for your types to fully work. As a result, you should have a `node_modules/@types/testing-library__jest-dom` directory. If you don't, then the types won't exist and that's why you're having issues.
-
-For instance, if you have a yarn project, hoisting happens automatically. However if you're using **pnpm**, `@types` are not hoisted automatically, you will have to add a `.npmrc` file with the following setting:
-
-```js
-// .npmrc
-public-hoist-pattern[]=@types*
-```
-
-Otherwise, installing `@types/testing-library__jest-dom` as a direct dependency should have the same effect and fix your issue.
-
-If you are still experiencing issues after making these changes, it's very likely that your `tsconfig.json` file contains specific type overrides, which means that it will ignore automatic types, for instance:
-
-```json
-{
-  "compilerOptions": {
-    "types": [
-      "node",
-      "mocha",
-    ]
-  }
-}
-```
-
-In that case, make sure to add `testing-library__jest-dom` to the `types` array:
-
-```json
-{
-  "compilerOptions": {
-    "types": [
-      "node",
-      "mocha",
-      "testing-library__jest-dom"
-    ]
-  }
-}
-```
+[jest-dom](https://github.com/testing-library/jest-dom) matchers are automatically included as well.
