The sample demonstrates how a [Retrieval Augmented Generation (RAG)](retrieval-augmented-generation-overview.md) application consumes a multimodal index (such as the one created by the [Azure portal multimodal functionality]((search-get-started-portal-image-search.md)) and renders both textual citations and associated image snippets in the response. The repository also showcases the full process of data ingestion and indexing through code, providing developers with a programmatic alternative to the Azure portal wizard.
