The HowTo structured data or content walks users through a set of steps to successfully complete a task, and can feature video, images, and text.
Properly marked up how-to pages may be eligible to have a rich result on Search and an Action on the Google Assistant, which can help your site reach the right users.

step (HowToStep or HowToSection): An array of HowToStep elements which comprise the full instructions. Each step element should correspond to an individual step in the instructions. Don't mark up non-step data such as a summary or introduction section.
