Paragraphs help you structure your content into more readable chunks, as compared to just a "wall of text". Insert other elements for even better readability: structure topics with chapters and procedures, add lists and tables, images and notes.
In semantic markup use the <p> element to create paragraphs. In Markdown, use blank lines to break text into paragraphs.
