Frequently Asked Questions
What is Markdown and what does it mean?
Markdown is a way to add structure and formatting to plain text. A few readable symbols mark headings, bold text, links, lists, tables, and other elements. A Markdown renderer can then turn that text into HTML or another display format.
What is a Markdown file (.md)?
A Markdown file is a plain text file with a .md or .markdown extension. You can open it in any text editor. A Markdown-aware editor also shows how the headings, links, lists, and other formatting will look when rendered.
What is Markdown formatting (or Markdown format)?
Markdown formatting is the small set of plain-text markers used to structure a document. Examples include # Heading, **bold**, *italic*, - list item, and [link text](url).
How do you use Markdown?
Write normal text, then add simple markers where you need structure. Put # before a top-level heading, wrap text in ** for bold, or begin a line with - for a bullet. The Markdown editor shows the rendered result while you type.
How do you bold text in Markdown?
Wrap the words in double asterisks or double underscores: **bold text** or __bold text__. Most Markdown renderers display either form as bold text.
How do you underline text in Markdown?
Standard Markdown has no underline marker. If your renderer allows inline HTML, use <u>underlined text</u>. Check your target platform first because some Markdown renderers remove raw HTML.
How do you make or create a table in Markdown?
Use pipes | to separate columns and a row of hyphens to separate the header from the body:
| Header 1 | Header 2 |
| -------- | -------- |
| Cell A | Cell B |For a larger table, use the Markdown table generator or paste the full document into the Markdown editor to align it.
How do you view and preview Markdown files in VS Code?
Open the .md file and choose Open Preview, or press Ctrl + Shift + V on Windows and Linux or Cmd + Shift + V on macOS. VS Code opens a rendered view of the current file.
Do I need to create an account?
No. The converters and editors work without an account or subscription.
