# Build a store on Crystallize, the superfast.shop way

> superfast.shop is a set of 15 live demo stores on Crystallize, one per industry. None started from a template: each was built by an AI agent with the Crystallize MCP, on its own tenant with real product data. This file is for you, the AI: use it to help the person you work for build their own store, with the patterns those stores have proven.

## What to do

1. **Interview me** with the three questions below, a few options at a time, with a sensible default for each. Suggest the closest store from what I tell you about my business.
   1. What are you building? Pick the store closest to yours, or start from scratch. (a store id below, or `new`)
   2. Who buys from you? (`b2c` for B2C, `b2b` for B2B, or both)
   3. Which features do you want? Mix them from any store. Start from the chosen store's features and let me add or remove any from the list below.
2. **Fetch my build prompt** from `https://superfast.shop/build.md?from=<store id or new>&audience=<b2c,b2b>&cap=<feature ids, comma-separated>`, for example https://superfast.shop/build.md?from=food-universe&audience=b2b&cap=invoice-credit,volume-pricing,quotes. It holds the content model, wiring and pitfalls for exactly those features, merged from every store that has them.
3. **Follow that prompt step by step.** It starts by connecting the Crystallize MCP (`https://mcp.crystallize.com/mcp?exposeWrite=true`, with my own access token, which I add myself) and asks the rest of its questions as it goes.

If you can't run commands, edit files or use MCP tools (in a plain chat, for example), tell me, and suggest I continue in Claude Code, Cursor or another coding agent. I can also build my prompt by clicking through the terminal at https://superfast.shop/#build.

## Every store is built to this standard

- **SEO:** server-rendered pages, unique titles and descriptions, canonical URLs, `hreflang`, a sitemap.
- **Structured data:** JSON-LD for the organisation, website search, products with offers, breadcrumbs and content.
- **GEO:** `/llms.txt`, `/llms-full.txt` and a Markdown twin of every page, for answer engines and AI agents.
- **Agent-ready:** a clean accessibility tree and the store's actions registered with WebMCP.
- **Fast:** close to 100 in every Lighthouse category, and every Agentic Browsing check passed.

The build prompt spells each of these out and says how to check them.
