+# CRM System v1.0
+
+> Self-hosted CRM for small sales teams (5–25 sales reps).
+> Stack: FastAPI + SQLAlchemy (async) + Alembic + Pydantic v2 + SQLite/PostgreSQL + Alpine.js + Tailwind + Docker + Coolify
+
+## Quick Start (Development)
+
+### 1. Clone and Setup
+
+```bash
+git clone <repo-url> crm-system
+cd crm-system
+
+# Create virtual environment
+python3 -m venv .venv
+source .venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt -r requirements-dev.txt
+```
+
+### 2. Configure Environment
+
+```bash
+# Copy template
+cp .env.example .env
+
+# Generate a secure AUTH_SECRET (min 32 chars)
+python3 -c "import secrets; print('AUTH_SECRET=' + secrets.token_urlsafe(48))" >> .env
+
+# Edit .env and set AUTH_SECRET (remove the placeholder line first)
+```
+
+### 3. Initialize Database
+
+```bash
+# Apply migrations
+alembic upgrade head
+
+# (Optional) Create migration after model changes
+# alembic revision --autogenerate -m "description"
+```
+
+### 4. Run Server
+
+```bash
+# Development with auto-reload
+uvicorn app.main:app --reload --port 8000
+
+# Production-like
+uvicorn app.main:app --host 0.0.0.0 --port 8000 --workers 2
+```
+
+Open:
+- API: http://localhost:8000
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+- Health: http://localhost:8000/health
+
+### 5. Bootstrap First User
+
+```bash
+curl -X POST http://localhost:8000/api/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@example.com",
+    "password": "secure-password-123",
+    "name": "First Admin"
+  }'
+```
+
+This creates the first user + a default org. After that, registration is disabled (use admin invite flow in v1.1).

+
+## Environment Variables
+
+| Variable | Required | Default | Description |
+|---|---|---|---|
+| `AUTH_SECRET` | ✅ | – | JWT signing secret (≥32 chars). Hard-fail if missing. |
+| `DATABASE_URL` | ❌ | `sqlite+aiosqlite:///./dev.db` | Async DB URL (aiosqlite or asyncpg) |
+| `JWT_ALGORITHM` | ❌ | `HS256` | JWT algorithm |
+| `JWT_EXPIRY_HOURS` | ❌ | `24` | Token lifetime |
+| `BCRYPT_ROUNDS` | ❌ | `12` | Password hashing cost |
+| `CORS_ORIGINS` | ❌ | `http://localhost:5500,http://localhost:8000` | Allowed origins (comma-separated, NO wildcards) |
+| `ENVIRONMENT` | ❌ | `development` | `development` or `production` |
+| `LOG_LEVEL` | ❌ | `INFO` | Python log level |
+
+## Architecture Decisions (ADR)
+
+- **JWT Library**: `python-jose[cryptography]==3.3.0` (pattern reuse from wochenplaner)
+- **Database**: SQLite (aiosqlite) for dev, PostgreSQL (asyncpg) for prod
+- **Auth**: Stateless JWT in localStorage, bcrypt password hashing (12 rounds)
+- **Security**: CORS whitelist (no wildcard), CSP middleware, no default admin user
+- **Async**: All routers/services/DB operations are async (SQLAlchemy 2.0 + aiosqlite)
+
+See `/a0/.a0/02-architecture.md` Section 13 for full lockdown decisions.
+
+## Deployment
+
+See `/a0/.a0/03-task-graph.json` Phase 4d for Docker + Coolify setup (out of scope for Phase 4a).
