-#### Babel 6
-
-Jest 24 dropped support for Babel 6. We highly recommend you to upgrade to Babel 7, which is actively maintained. However, if you cannot upgrade to Babel 7, either keep using Jest 23 or upgrade to Jest 24 with `babel-jest` locked at version 23, like in the example below:
-
-```
-"dependencies": {
-  "babel-core": "^6.26.3",
-  "babel-jest": "^23.6.0",
-  "babel-preset-env": "^1.7.0",
-  "jest": "^24.0.0"
-}
-```

-While we generally recommend using the same version of every Jest package, this workaround will allow you to continue using the latest version of Jest with Babel 6 for now.

 ### Using webpack
 
 Jest can be used in projects that use [webpack](https://webpack.github.io/) to manage assets, styles, and compilation. webpack does offer some unique challenges over other tools. Refer to the [webpack guide](https://jestjs.io/docs/en/webpack) to get started.
 
 ### Using TypeScript
 
-Jest supports TypeScript out of the box, via Babel.
+Jest supports TypeScript, via Babel. First make sure you followed the instructions on [using Babel](#using-babel) above. Next install the `@babel/preset-typescript` via `yarn`:
+
+```bash
+yarn add --dev @babel/preset-typescript
+```
+
+Then add `@babel/preset-typescript` to the list of presets in your `babel.config.js`.
+
+```diff
+// babel.config.js
+module.exports = {
+  presets: [
+    ['@babel/preset-env', {targets: {node: 'current'}}],
++    '@babel/preset-typescript',
+  ],
+};
+```
 
-However, there are some caveats to using Typescript with Babel, see http://artsy.github.io/blog/2017/11/27/Babel-7-and-TypeScript/. Another caveat is that Jest will not typecheck your tests. If you want that, you can use [ts-jest](https://github.com/kulshekhar/ts-jest).
+Note, there are some [caveats](https://babeljs.io/docs/en/next/babel-plugin-transform-typescript.html#caveats) to using TypeScript with Babel. Because TypeScript support in Babel is just transpilation, Jest will not type-check your tests as they are ran. If you want that, you can use [ts-jest](https://github.com/kulshekhar/ts-jest).
