This document introduces IFTTT (If This Then That), a service that allows users to create recipes to automatically trigger actions across different online services and apps. Recipes have a trigger, such as checking into Foursquare, that then trigger an action, like adding the check-in details to a note in Evernote. The document explains how IFTTT works with channels that each have triggers and actions, how to browse popular recipes or create your own, and how to get started using IFTTT by signing up on their website.
