WalkMe is an online tool that allows you to create step-by-step guides that show your customer, or really any website visitor, how to do what you want them to do. It inserts little instruction bubbles that guide your user to the next task. This is a very nice tool for building walkthrough and tutorials for a website.
From their site:
WalkMe enables website owners and app developers to easily create multiple interactive on-screen Walk-Thrus that help users to quickly and easily complete even the most complex tasks.
Users receive clear and error-proof on-screen instructions, displayed as sequential balloon hints within the website or app, while they perform the actual process from start to finish.
