Adobe InDesign is a layout software that takes images and text and lay them out across pages. InDesign is best used for working with multiple page documents like books, magazines, brochures, portfolios and can even be used to create business cards, letterheads, posters, and flyers.
Graphic designers and production artists are the primary users of this desktop publishing software. It can also be used in conjunction with other Adobe products primarily Photoshop and Illustrator.
