An ideal content editor produces structured, semantically meaningful documents, but does so in a way that is easy for users to understand. ProseMirror tries to bridge the gap between Markdown text editing and classical WYSIWYG editors. It does this by implementing a WYSIWYG-style editing interface for document data structures more constrained and structured than plain HTML. You can customize the shape and structure of the documents your editor creates, and tailor them to your application's needs.

Don’t worry, you don’t need to know anything about flying—it’s all automated. No knowledge of flight dynamics, weather, or navigation is required. Just push the right buttons on the dash and the computer will take care of the rest. It’s as easy as driving a car! I hope you’d say, “thanks but no thanks.” Sure, someday that will be a reality, but you realize that right now flying is a much more complex operation than driving.
