+## Quick Start (Docker)
+
+```bash
+# 1. Iniciar toda la stack
+cd crawlapi
+docker-compose up --build
+
+# 2. Crear seed data (en otra terminal)
+export DATABASE_URL="postgres://crawlapi:crawlapi@localhost:5432/crawlapi"
+source "$HOME/.cargo/env"
+cargo run -p api --bin seed
+
+# 3. Servicios disponibles:
+# API:        http://localhost:3000
+# Frontend:   http://localhost
+# MinIO:      http://localhost:9001 (minioadmin/minioadmin)
+# Prometheus: http://localhost:9090
+# Grafana:    http://localhost:3001 (admin/admin)
+```
+
+## CI/CD (GitHub Actions)
+
+```bash
+# En cada push a main:
+# 1. cargo fmt --check
+# 2. cargo clippy -- -D warnings
+# 3. cargo test --workspace
+# 4. cargo audit
+# 5. Docker build + push a registry
+# 6. Deploy a staging
+# 7. Smoke tests
+# 8. Deploy a production (solo en tags v*)
+```
+
+**Workflows:**
+- `.github/workflows/ci.yml` — Test, build, push images
+- `.github/workflows/deploy.yml` — Deploy a staging y production
+
+## Kubernetes
+
+```bash
+# Instalar cert-manager primero
+kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.0/cert-manager.yaml
+
+# Deploy todo
+cd k8s
+kubectl apply -f namespace.yaml
+kubectl apply -f cert-manager.yaml
+kubectl apply -f secrets.yaml
+kubectl apply -f postgres.yaml
+kubectl apply -f redis.yaml
+kubectl apply -f minio.yaml
+kubectl apply -f api.yaml
+kubectl apply -f worker.yaml
+kubectl apply -f frontend.yaml
+
+# Workers auto-scale con HPA (3-20 réplicas)
+kubectl get hpa -n crawlapi
+```
+
+## Load Testing (k6)
+
+```bash
+cd load-tests
+
+# Smoke test (1 VU, 1 min)
+k6 run smoke.js
+
+# Load test (ramp up a 20 VUs, 14 min)
+k6 run load.js
+
+# Stress test (hasta 200 VUs)
+k6 run stress.js
+
+# Screenshot test (5 VUs concurrentes)
+k6 run screenshot.js
+```
+
+## Tests
+
+```bash
+# Unit tests
+cargo test
+
+# E2E tests
+cd e2e && npm install && npx playwright test
+```

+# Terms of Service
+
+Last updated: April 29, 2026
+
+## 1. Acceptance of Terms
+
+By accessing or using Crawl API ("the Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.
+
+## 2. Description of Service
+
+Crawl API provides headless browser automation and web scraping tools via a REST API. The Service allows users to extract data, take screenshots, generate PDFs, and perform other automated web interactions.
+
+## 3. Account Registration
+
+You must provide accurate information when creating an account. You are responsible for maintaining the security of your account credentials and API keys.
+
+## 4. Acceptable Use
+
+You agree not to use the Service to:
+- Scrape websites that explicitly prohibit scraping in their robots.txt or terms of service
+- Access or attempt to access non-public areas of websites without authorization
+- Violate any applicable laws or regulations
+- Distribute malware or engage in fraudulent activities
+- Overwhelm or damage third-party websites (rate limiting applies)
+
+## 5. API Usage and Credits
+
+The Service operates on a credit-based system. Each API endpoint consumes 1 credit per call. Credits are non-refundable and expire according to your subscription plan.
+
+## 6. Payment and Billing
+
+Paid plans are billed in advance on a monthly or annual basis. You can cancel your subscription at any time. Refunds are provided at our sole discretion.
+
+## 7. Data Privacy
+
+We process data in accordance with our Privacy Policy. We do not store scraped content permanently unless explicitly requested.

+We reserve the right to suspend or terminate your account for violation of these terms or for any other reason at our discretion.
+
+## 10. Changes to Terms
+
+We may update these terms from time to time. Continued use of the Service after changes constitutes acceptance of the new terms.
