# Collection Display

The [NFTCollectionDisplay view](https://github.com/onflow/flow-nft/blob/461524168b50d015fffec23f33bba5adabdbe791/contracts/MetadataViews.cdc#L558C34-L558C34) tells platforms how to show a Collection. Flowty relies on the following fields from this view:

* **Name:** What is this collection's name? In the absence of this view, we will use a collection's Contract name.
* **Description (Optional):** A brief description of your collection.
* **External URL (Optional):** A backlink to your collection's native website/app for users to discover more about your collection.
* **Square Image:** The image to use for your collection's thumbnail.
* **Banner Image:** The image to use as the background for your collection banner on Flowty's collection page. [**Recommended Dimensions are 1200x630**](https://github.com/onflow/flow-nft/blob/4c0c684baed98e2ffd7a8f9d27973c1db5dd1239/contracts/MetadataViews.cdc#L571).
* **Socials:** A set of social pages for your collection. Currently Flowty only supports Twitter links. Give us a shout if you want to see others added!
