 Some build tools will require additional setup.
 
-##### React, Next.js, and Webpack
-
-The [Webpack v5](https://webpack.js.org/blog/2020-10-10-webpack-5-release/) bundler used by Next.js and Create React App [no longer provides Node polyfills](https://webpack.js.org/blog/2020-10-10-webpack-5-release/#automatic-nodejs-polyfills-removed), so you'll need to include these modules yourself to satisfy RainbowKit's peer dependencies. Create React App specifically requires that you polyfill `Buffer`.
-
-Reference our [Next.js Webpack Config](https://github.com/rainbow-me/rainbowkit/blob/main/examples/with-next/next.config.js), [Next.js App Router Webpack Config](https://github.com/rainbow-me/rainbowkit/blob/main/examples/with-next-app/next.config.js), and [Create React App polyfills](https://github.com/rainbow-me/rainbowkit/blob/main/examples/with-create-react-app/src/polyfills.ts) samples for configuration guidance for your project.
-
-##### Vite
-
-The [Vite](https://vitejs.dev) bundler doesn't provide Node polyfills, so you'll need to include polyfills for `global`, `Buffer` and `process.env`. As an example, you can reference the [polyfills in our sample Vite project](https://github.com/rainbow-me/rainbowkit/tree/main/examples/with-vite/src/polyfills.ts).
-
 ##### Remix
 
 When using [Remix](https://remix.run), you must polyfill `buffer`, `events` and `http` modules. Reference the Remix configuration below, or [our sample Remix project](https://github.com/rainbow-me/rainbowkit/blob/main/examples/with-remix).
