Pinterest is a social media application that allows users to create boards to organize and share items they find online, called pins. Users can pin recipes, crafts, fashion tips, and other content and categorize pins onto boards. It functions as a web-based community for open sharing of information. Pinterest can be used educationally by having students create a class account to pin educational resources to topic boards, or to compile research findings. The tutorial then explains how to sign up, create boards to organize bookmarks, and share pins and boards with others.
