# Catalog guides

> Task-based walkthroughs for building listings, pricing them, and deciding what they draw from.

Each guide below walks one task from start to finish. For what a single view or tab does, see [Catalog](/docs/catalog/overview) under **Navigating in TWICE**; for how the data is modelled, see the [Listings](/docs/concepts/catalog/listings) and [Availability](/docs/concepts/catalog/availability) concepts.

The catalog is where the inventory you hold becomes something a customer can buy. A listing is the offer; the stock items and SKUs behind it are what actually go out the door. Guides for that side of the line live under [Inventory guides](/docs/guides/inventory/overview).

## Building a listing

## Pricing and offers

## Availability and rules
