+<Steps>

+
+### Create a monorepo
+
+If you don't have an existing project, use [create-turbo](/docs/getting-started/installation) to create a new monorepo:

+<PackageManagerTabs>
+
+<Tab value="pnpm">
+
+```bash title="Terminal"
+pnpm dlx create-turbo@latest
+```
+
+</Tab>

+```bash title="Terminal"
+yarn dlx create-turbo@latest

+
+```bash title="Terminal"
+bunx create-turbo@latest
+```
+
+</Tab>
+</PackageManagerTabs>
+
+</Step>
+
+<Step>
+
+### Add TailwindCSS to your application
+
+[Follow TailwindCSS's guides](https://tailwindcss.com/docs/installation/using-vite) to set up TailwindCSS for your frontend framework.
+
+Once completed, we can integrate your UI package into the applications.
+
+</Step>
+
+<Step>
+
+### Create a shared TailwindCSS configuration package
+
+First, build an [Internal Package](https://turborepo.com/docs/core-concepts/internal-packages) with four files:
+
+<Tabs items={["package.json", "tailwind.config.ts", "tsconfig.json", "postcss.config.js (Optional)"]}>
+
+<Tab value="package.json">
+
+This `package.json` installs TailwindCSS so we can create the configuration file and exports the configuration file for use in the rest of the repository.
+
+```json title="./packages/tailwind-config/package.json"
+{
+  "name": "@repo/tailwind-config",
+  "version": "0.0.0",
+  "private": true,
+  "exports": {
+    ".": "./tailwind.config.ts"
+  },
+  "devDependencies": {
+    "@repo/typescript-config": "workspace:*",
+    "tailwindcss": "^4.1.5"
+  }
+}
+```
+
+</Tab>
+
+<Tab value="tailwind.config.ts">
+
+This `tailwind.config.ts` will be shared to the libraries and applications in the repository.
+
+```ts title="./packages/tailwind-config/tailwind.config.ts"
+import type { Config } from 'tailwindcss';
+
+const config: Omit<Config, 'content'> = {
+  darkMode: 'class',
+};
+export default config;
+```
+
+</Tab>
+
+<Tab value="tsconfig.json">
+
+A simple TypeScript configuration file so we can use TypeScript for the `tailwind.config.ts`
+
+```ts title="./packages/tailwind-config/tconfig.json"
+{
+  "extends": "@repo/typescript-config/base.json",
+  "include": ["."],
+  "exclude": ["dist", "build", "node_modules"]
+}
+```
+
+</Tab>
+
+<Tab value="postcss.config.js (Optional)">
+
+If your frontends need a PostCSS configuration file, you can create one to share.
+
+```js title="./packages/tailwind-config/postcss.config.js"
+export const postcssConfig = {
+  plugins: {
+    '@tailwindcss/postcss': {},
+  },
+};
+```
+
+</Tab>
+</Tabs>
+
+</Step>
+
+<Step>
+
+### Create the UI package
+
+You can now build the components you share to your applications.
+
+For a full example, [visit the source code for `@repo/ui` package in the TailwindCSS example](https://github.com/vercel/turborepo/tree/main/examples/with-tailwind/packages/ui). The files required for your TailwindCSS setup are below.
+
+<Tabs items={["package.json", "turbo.json", "tailwind.config.ts", "styles.css"]}>
+
+<Tab value="package.json">
+
+The `package.json` installs the dependencies for the package, sets up scripts for development and build environments, and marks the exports for the package.
+
+```json title="./packages/ui/package.json"
+{
+  "exports": {
+    "./styles.css": "./dist/index.css",
+    "./*": "./dist/*.js"
+  },
+  "scripts": {
+    "build:styles": "tailwindcss -i ./src/styles.css -o ./dist/index.css",
+    "build:components": "tsc",
+    "dev:styles": "tailwindcss -i ./src/styles.css -o ./dist/index.css --watch",
+    "dev:components": "tsc --watch"
+  },
+  "devDependencies": {
+    "@repo/tailwind-config": "workspace:*",
+    "@tailwindcss/cli": "^4.1.5",
+    "@tailwindcss/postcss": "^4.1.5",
+    "autoprefixer": "^10.4.20",
+    "tailwindcss": "^4.1.5"
+  }
+}
+```

+<Callout type="good-to-know">
+  Above, we've only included the code related to setting up Tailwind. The full
+  package.json is
+  [here](https://github.com/vercel/turborepo/tree/main/examples/with-tailwind/packages/ui/package.json).

+
+Install the packages you've created into your application.

+<PackageManagerTabs>
+
+<Tab value="pnpm">
+
+```bash title="Terminal"
