# What are collections? Imagine one of the following cases: * you own an online shop, and want to add your product assortment to a Twise * you rent/sell properties, and would want to add your listings to a Twise * you are a event listing site (tours, concerts, experiences, etc.), and want to add events to a Twise To support such cases, you can import a special kind of content we call a collection. A Twise will intelligently include your products in the conversation when it is relevant. Using collections, a Twise can transform into a product discovery tool using natural language. Currently, we support the following collection types: * `Product` * `Event` * `Villa` * `Page` A Twise currently is limited to use one collection type at a time. #### How to add content to a collection? * Using an API * [Adding events](/collections-api-events.md) * Importing a Google Merchant XML Feed * [Importing a Twise XML Feed](/importing-a-collection-via-a-twise-xml-feed.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
