Lightweight markup language

A lightweight markup language is a simple way to write formatted text using plain text symbols, making it easy to read and write without complex tools. It allows users to add structure—like headings, lists, and links—using simple symbols (e.g., hash signs for headers or asterisks for bullet points). This approach is widely used for creating documents, web content, and notes because it's easy to learn, quick to write, and can be converted into well-structured, styled formats such as HTML or PDF. Examples include Markdown and reStructuredText.
