+# Project Setup
+
+Standard patterns for new Nuxt projects: CI, ESLint, package scripts.
+
+## CI Workflow
+
+```yaml
+# .github/workflows/ci.yml
+name: CI
+on: [push, pull_request]
+
+jobs:
+  ci:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: pnpm/action-setup@v4
+      - uses: actions/setup-node@v4
+        with: {node-version: 22, cache: pnpm}
+      - run: pnpm install --frozen-lockfile
+      - run: pnpm prepare
+      - run: pnpm lint
+      - run: pnpm typecheck
+      - run: pnpm test # if tests exist
+```
+
+**With env vars:**
+
+```yaml
+env:
+  DATABASE_URL: postgresql://test:test@localhost:5432/test
+  API_KEY: test
+```
+
+## ESLint Config
+
+```js
+// eslint.config.mjs
+import antfu from '@antfu/eslint-config'
+import withNuxt from './.nuxt/eslint.config.mjs'
+
+export default withNuxt(
+  antfu({
+    formatters: true,
+    vue: true,
+    pnpm: true,
+    ignores: ['.eslintcache', 'cache/**', '.claude/**', 'README.md', 'docs/**'],
+  }),
+)
+```
+
+**For monorepos, add:**
+
+```js
+ignores: ['apps/web/.nuxt/**', 'packages/**/dist/**']
+```
+
+## Package Scripts
+
+```json
+{
+  "scripts": {
+    "dev": "nuxt dev",
+    "build": "nuxt build",
+    "preview": "nuxt preview",
+    "prepare": "nuxt prepare",
+    "lint": "eslint . --cache",
+    "lint:fix": "eslint . --fix --cache",
+    "typecheck": "nuxt typecheck"
+  }
+}
+```
+
+## Key Conventions
+
+| Convention      | Standard                                              |
+| --------------- | ----------------------------------------------------- |
+| Package manager | pnpm with `--frozen-lockfile` in CI                   |
+| Node version    | 22-24                                                 |
+| ESLint base     | @antfu/eslint-config                                  |
+| Formatter       | Via ESLint (`formatters: true`), no separate Prettier |
+| Cache           | `--cache` flag on lint scripts                        |
+| Prepare step    | Required before lint/typecheck in CI                  |
+
+## NuxtHub Deployment
+
+```yaml
+# .github/workflows/nuxthub.yml
+name: Deploy to NuxtHub
+on: push
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    permissions: {contents: read, id-token: write}
+    steps:
+      - uses: actions/checkout@v4
+      - uses: pnpm/action-setup@v4
+      - uses: actions/setup-node@v4
+        with: {node-version: 22, cache: pnpm}
+      - run: pnpm install
+      - uses: nuxt-hub/action@v2
+        with:
+          project-key: your-project-key
+```
