+
+## Quick Start
+
+### 1. Install dependencies
+
+```bash
+pnpm install
+```
+
+### 2. Configure environment variables
+
+Copy the example env files:
+
+```bash
+# Root env (database, product name, URL)
+cp .env.example .env
+
+# Web app env (auth, billing, email, storage, AI, etc.)
+cp apps/web/.env.example apps/web/.env.local
+```
+
+**Root `.env`** — minimum required variables:
+
+```env
+DATABASE_URL="postgresql://turbostarter:turbostarter@localhost:5440/core"
+PRODUCT_NAME="TurboStarter"
+URL="http://localhost:3000"
+DEFAULT_LOCALE="en"
+```
+
+> **Note:** The database port is `5440` (mapped from Docker), not the default `5432`.
+
+**`apps/web/.env.local`** — key variables to configure:
+
+| Variable | Description | Required |
+|---|---|---|
+| `BETTER_AUTH_SECRET` | Auth token signing secret | Yes |
+| `NEXT_PUBLIC_AUTH_PASSWORD` | Enable password auth (`true`/`false`) | Yes |
+| `NEXT_PUBLIC_URL` | Public URL of the web app | Yes |
+| `STRIPE_SECRET_KEY` | Stripe key (if using Stripe billing) | Optional |
+| `RESEND_API_KEY` | Resend key (if using Resend email) | Optional |
+| `S3_*` | S3/MinIO storage credentials | Optional |
+| `OPENAI_API_KEY` | OpenAI key (if using AI features) | Optional |
+
+For local MinIO storage, use these S3 settings in `apps/web/.env.local`:
+
+```env
+S3_REGION="us-east-1"
+S3_BUCKET="uploads"
+S3_ENDPOINT="http://localhost:9000"
+S3_ACCESS_KEY_ID="minioadmin"
+S3_SECRET_ACCESS_KEY="minioadmin"
+```
+
+See `apps/web/.env.example` for the full list of available variables.
+
+### 3. Start infrastructure (Docker Compose)
+
+Start PostgreSQL and MinIO:
+
+```bash
+docker compose up -d
+```
+
+Wait for services to be healthy:
+
+```bash
+docker compose up -d --wait
+```
+
+Or use the built-in shortcut:
+
+```bash
+pnpm services:start
+```
+
+### 4. Set up the database
+
+Run migrations and seed data:
+
+```bash
+pnpm services:setup
+```
+
+This runs `docker compose up -d --wait`, then applies database migrations and seeds initial data.
+
+### 5. Start development
+
+```bash
+pnpm dev
+```
+
+The web app will be available at **http://localhost:3000**.
+
