+# Repository Structure
+
+Detailed guidance on structuring a Turborepo monorepo.
+
+## Workspace Configuration
+
+### pnpm (Recommended)
+
+```yaml
+# pnpm-workspace.yaml
+packages:
+  - "apps/*"
+  - "packages/*"
+```
+
+### npm/yarn/bun
+
+```json
+// package.json
+{
+  "workspaces": ["apps/*", "packages/*"]
+}
+```
+
+## Root package.json
+
+```json
+{
+  "name": "my-monorepo",
+  "private": true,
+  "packageManager": "pnpm@9.0.0",
+  "scripts": {
+    "build": "turbo run build",
+    "dev": "turbo run dev",
+    "lint": "turbo run lint",
+    "test": "turbo run test"
+  },
+  "devDependencies": {
+    "turbo": "latest"
+  }
+}
+```
+
+Key points:
+
+- `private: true` - Prevents accidental publishing
+- `packageManager` - Enforces consistent package manager version
+- **Scripts only delegate to `turbo run`** - No actual build logic here!
+- Minimal devDependencies (just turbo and repo tools)
+
+## Always Prefer Package Tasks
+
+**Always use package tasks. Only use Root Tasks if you cannot succeed with package tasks.**
+
+```json
+// packages/web/package.json
+{
+  "scripts": {
+    "build": "next build",
+    "lint": "eslint .",
+    "test": "vitest",
+    "typecheck": "tsc --noEmit"
+  }
+}
+
+// packages/api/package.json
+{
+  "scripts": {
+    "build": "tsc",
+    "lint": "eslint .",
+    "test": "vitest",
+    "typecheck": "tsc --noEmit"
+  }
+}
+```
+
+Package tasks enable Turborepo to:
+
+1. **Parallelize** - Run `web#lint` and `api#lint` simultaneously
+2. **Cache individually** - Each package's task output is cached separately
+3. **Filter precisely** - Run `turbo run test --filter=web` for just one package
+
+**Root Tasks are a fallback** for tasks that truly cannot run per-package:
+
+```json
+// AVOID unless necessary - sequential, not parallelized, can't filter
+{
+  "scripts": {
+    "lint": "eslint apps/web && eslint apps/api && eslint packages/ui"
+  }
+}
+```
+
+## Root turbo.json
+
+```json
+{
+  "$schema": "https://turborepo.dev/schema.v2.json",
+  "tasks": {
+    "build": {
+      "dependsOn": ["^build"],
+      "outputs": ["dist/**", ".next/**", "!.next/cache/**"]
+    },
+    "lint": {},
+    "test": {
+      "dependsOn": ["build"]
+    },
+    "dev": {
+      "cache": false,
+      "persistent": true
+    }
+  }
+}
+```
+
+## Directory Organization
+
+### Grouping Packages
+
+You can group packages by adding more workspace paths:
+
+```yaml
+# pnpm-workspace.yaml
+packages:
+  - "apps/*"
+  - "packages/*"
+  - "packages/config/*"    # Grouped configs
+  - "packages/features/*"  # Feature packages
+```
+
+This allows:
+
+```
+packages/
+├── ui/
+├── utils/
+├── config/
+│   ├── eslint/
+│   ├── typescript/
+│   └── tailwind/
+└── features/
+    ├── auth/
+    └── payments/
+```
+
+### What NOT to Do
+
+```yaml
+# BAD: Nested wildcards cause ambiguous behavior
+packages:
+  - "packages/**"  # Don't do this!
+```
+
+## Package Anatomy
+
+### Minimum Required Files
+
+```
+packages/ui/
+├── package.json    # Required: Makes it a package
+├── src/            # Source code
+│   └── button.tsx
+└── tsconfig.json   # TypeScript config (if using TS)
+```
+
+### package.json Requirements
+
+```json
+{
+  "name": "@repo/ui",           // Unique, namespaced name
+  "version": "0.0.0",           // Version (can be 0.0.0 for internal)
+  "private": true,              // Prevents accidental publishing
+  "exports": {                  // Entry points
+    "./button": "./src/button.tsx"
+  }
+}
+```
+
+## TypeScript Configuration
+
+### Shared Base Config
+
+Create a shared TypeScript config package:
+
+```
+packages/
+└── typescript-config/
+    ├── package.json
+    ├── base.json
+    ├── nextjs.json
+    └── library.json
+```
+
+```json
+// packages/typescript-config/base.json
+{
+  "compilerOptions": {
+    "strict": true,
+    "esModuleInterop": true,
+    "skipLibCheck": true,
+    "moduleResolution": "bundler",
+    "module": "ESNext",
+    "target": "ES2022"
+  }
+}
+```
+
+### Extending in Packages
+
+```json
+// packages/ui/tsconfig.json
+{
+  "extends": "@repo/typescript-config/library.json",
+  "compilerOptions": {
+    "outDir": "dist",
+    "rootDir": "src"
+  },
+  "include": ["src"],
+  "exclude": ["node_modules", "dist"]
+}
+```
+
+### No Root tsconfig.json
+
+You likely don't need a `tsconfig.json` in the workspace root. Each package should have its own config extending from the shared config package.
+
+## ESLint Configuration
+
+### Shared Config Package
+
+```
+packages/
+└── eslint-config/
+    ├── package.json
+    ├── base.js
+    ├── next.js
+    └── library.js
+```
+
+```json
+// packages/eslint-config/package.json
+{
+  "name": "@repo/eslint-config",
+  "exports": {
+    "./base": "./base.js",
+    "./next": "./next.js",
+    "./library": "./library.js"
+  }
+}
+```
+
+### Using in Packages
+
+```js
+// apps/web/.eslintrc.js
+module.exports = {
+  extends: ["@repo/eslint-config/next"],
+};
+```
+
+## Lockfile
+
+A lockfile is **required** for:
+
+- Reproducible builds
+- Turborepo to understand package dependencies
+- Cache correctness
+
+Without a lockfile, you'll see unpredictable behavior.
