 ###4.1 Indexing Your First Images
 
-Built for scalability, ViSearch API enables fast and accurate searches on high volume of images. Before making your first image search, you need to prepare a list of images and index them into ViSearch by calling the ```insert``` endpoint. Each image must have a distinct name (```imName```) which serves as this image's unique identifier and a publicly downloadable URL (```imUrl```). ViSearch will parallelly fetch and index your images from the given URLs. You can check the status of this process using instructions described in [Section 4.5](#45-check-indexing-status). After the image indexes are built, you can start searching for [similar images using the unique identifier](#51-pre-indexed-search), [using a color](#52-color-search), or [using another image](#53-upload-search).
