 Let's go over the key dependencies:
 
-- **react-instantsearch-core** - Provides InstantSearch hooks and components for React Native
-- **typesense-instantsearch-adapter** - Connects InstantSearch with Typesense
+- **react-instantsearch-core** - Provides [InstantSearch](https://github.com/algolia/instantsearch) hooks and components for React Native. InstantSearch is an open-source UI library by Algolia for building search interfaces that works with any search backend through adapters.
+- **typesense-instantsearch-adapter** - Connects InstantSearch with Typesense as the search engine
 
 :::tip Note
 React Native can use `react-instantsearch-core` with the [`typesense-instantsearch-adapter`](https://github.com/typesense/typesense-instantsearch-adapter), just like web frameworks. This gives you access to powerful InstantSearch hooks and widgets. Alternatively, you can make direct API calls to Typesense using the Fetch API for a lighter implementation.
