 * Steps 1 and 2 are only used for file upload.
 * Downloading URLs to your blob storage is not illustrated in this diagram. After web pages are downloaded from the internet and uploaded to blob storage, steps 3 onward are the same.
-* Two indexers, two indexes, two data sources and a [custom skill](/azure/search/cognitive-search-custom-skill-interface) are created in the Azure AI Search resource.
-* The chunks container is created in the blob storage.
-* If the schedule triggers the ingestion, the ingestion process starts from step 7.
-*  Azure OpenAI's `preprocessing-jobs` API implements the [Azure AI Search customer skill web API protocol](/azure/search/cognitive-search-custom-skill-web-api), and processes the documents in a queue. 
-* Azure OpenAI:
-    1. Internally uses the first indexer created earlier to crack the documents.
-    1. Uses a heuristic-based algorithm to perform chunking. It honors table layouts and other formatting elements in the chunk boundary to ensure the best chunking quality.
-    1. If you choose to enable vector search, Azure OpenAI uses the selected embedding setting to vectorize the chunks.
-* When all the data that the service is monitoring are processed, Azure OpenAI triggers the second indexer.
-* The indexer stores the processed data into an Azure AI Search service.
+* One indexer, one index, and one data source in the Azure AI Search resource is created using prebuilt skills and [integrated vectorization](/azure/search/vector-search-integrated-vectorization.md).
+* Azure AI Search handles the extraction, chunking, and vectorization of chunked documents through integrated vectorization. If a scheduling interval is specified, the indexer will run accordingly.
