Concept
Simply put, it is a simple and unobtrusive way to show the user how to use a specific product or development.
Properly organized onboarding should easily guide the client from the moment of first acquaintance to full use.
Example
Imagine that a team is developing an application, let's say it is a DEX platform with a gasless function in an EVM environment. Ideal onboarding is when the product talks about itself and naturally guides the user through the necessary screens (in some places with tooltips), demonstrating the ease of operation and financial benefits of this technology.
