 # newspack-listings
 
-A new thing.
+[![semantic-release](https://img.shields.io/badge/%20%20%F0%9F%93%A6%F0%9F%9A%80-semantic--release-e10079.svg)](https://github.com/semantic-release/semantic-release) [![newspack-listings](https://circleci.com/gh/Automattic/newspack-listings/tree/master.svg?style=shield)](https://circleci.com/gh/Automattic/newspack-listings)
+
+Create reusable content as listings and add them to lists wherever core blocks can be used. Create static, curated lists or dynamic, auto-updating lists with optional "load more" functionality. Edit display options to control how the list looks and behaves for readers. Compatible with [AMP](https://amp.dev/).
+
+## Usage
+
+1. Activate this plugin.
+2. In the WP admin dashboard, look for Listings.
+3. Create and publish listings of any type. Listings can contain any core blocks as content.
+4. Optionally tag or categorize your listings to keep them organized, even across different listing types.
+5. Once at least one listing is published, add a Curated List block to any post or page.
+6. Choose Specific Listings mode to create a static list, or Query mode to create a dynamic list which will automatically update itself when new listings matching the query options are published.
+7. Edit list options to control the list's display and behavior.
+
+For more detailed instructions, refer to the [public documentation for Newspack Listings](https://newspack.pub/support/listings/).
 
 ## Development
 
 Run `composer update && npm install`.
 
 Run `npm run build`.
+
+Each listing type is a separate custom post type. Configuration is in `includes/newspack-listings-core.php`.
+
+Metadata for listing CPTs is synced from certain blocks in the post content. See configuration in `includes/newspack-listings-core.php` for details.
