 # Market App
 
-Product browsing and marketplace application for the Rose Ash cooperative.
-
-## Overview
-
-The Market app is one of three microservices split from the original coop monolith:
-
-- **coop** (:8000) - Blog, calendar, auth, settings
-- **market** (:8001) - Product browsing, categories, product detail
-- **cart** (:8002) - Shopping cart, orders, payments
+Product browsing and marketplace service for the Rose Ash cooperative. Displays products scraped from Suma Wholesale.
 
 ## Architecture
 
-- **Framework:** Quart (async Flask)
-- **Database:** PostgreSQL 16 with SQLAlchemy 2.0 (async)
-- **Cache:** Redis (tag-based page cache)
-- **Frontend:** HTMX + Jinja2 + Tailwind CSS
-- **Data:** Products scraped from Suma Wholesale
+One of four Quart microservices sharing a single PostgreSQL database:
 
-## Blueprints
+| App | Port | Domain |
+|-----|------|--------|
+| blog (coop) | 8000 | Auth, blog, admin, menus, snippets |
+| **market** | 8001 | Product browsing, Suma scraping |
+| cart | 8002 | Shopping cart, checkout, orders |
+| events | 8003 | Calendars, bookings, tickets |
 
-- `bp/market/` - Market root (navigation, category listing)
-- `bp/browse/` - Product browsing with filters and infinite scroll
-- `bp/product/` - Product detail pages
-- `bp/api/` - Product sync API (used by scraper)

-    # Install dependencies
-    pip install -r requirements.txt
+## Cross-App Integration
 
-    # Set environment variables
-    export $(grep -v '^#' .env | xargs)
-
-    # Run migrations
-    alembic upgrade head
-
-    # Scrape products
-    bash scrape.sh
-
-    # Run the dev server
-    hypercorn app:app --reload --bind 0.0.0.0:8001
+- **Cart:** "Add to cart" posts to cart app. Cart widget fetched via internal API.
+- **Blog:** Post/page data fetched via internal API for page-scoped marketplaces.
+- **Glue:** MarketPlace uses generic containers (`container_type + container_id`) to attach to pages without FK coupling.
 
 ## Scraping
 
-    # Full scrape (max 50 pages, 200k products, 8 concurrent)
-    bash scrape.sh
+```bash
+# Full scrape (Suma Wholesale catalogue)
+bash scrape.sh
 
-    # Test scraping
-    bash scrape-test.sh
+# Test scraping (limited)
+bash scrape-test.sh
+```
+
+## Running
+
+```bash
+export DATABASE_URL_ASYNC=postgresql+asyncpg://user:pass@localhost/coop
+export REDIS_URL=redis://localhost:6379/0
+export SECRET_KEY=your-secret-key
+export SUMA_USER=your-suma-username
+export SUMA_PASSWORD=your-suma-password
+
+hypercorn app:app --reload --bind 0.0.0.0:8001
+```
