help

Online help is a form of user assistance that provides topic-oriented, procedural or reference information designed to assist in using a software application, web application or operating system. Online help linked to the application's state (what the user is doing) is called Context-sensitive help.
The help information can be created using help authoring tools or component content management systems and can be delivered in a wide variety of proprietary and open-standard formats. Help of this kind has largely replaced printed documentation.
Interactive help can also be provided via virtual assistants and Chatbot systems.
