How can I create and open a Markdown file?
A markdown file is a plain-text document that uses simple symbols to add formatting to written content. You can create one with a basic text editor and save it using the .md extension. To open or edit it, you can use editors such as Visual Studio Code, Notepad++, or other Markdown-supported applications. Many tools also provide a preview mode so you can see how headings, links, lists, and other elements will appear after formatting. This makes Markdown useful for documentation and technical content.
