Check our videoThe CHM file format was developed by Microsoft for storing and displaying online help documentation, combining multiple HTML pages into a single compressed file. It is commonly opened using Microsoft's HTML Help Viewer, but third-party tools like 7-Zip or SumatraPDF can also extract or view CHM files. The format supports a hierarchical table of contents, full-text search, and embedded multimedia, making it a versatile solution for organizing and accessing help content efficiently.
Markdown Documentation (MD) is a lightweight markup language used to format plain text with simple syntax for easy conversion to HTML and other formats. It is widely supported by text editors like VS Code, Typora, and GitHub, as well as tools such as Pandoc and Markdown parsers. The format uses symbols like `#`, `*`, and `>` for headings, lists, and blockquotes, while advanced features include tables, code blocks, and inline HTML for customization.
