FAQ
Can I write HTML inside Markdown?
For safety, HTML tags are shown as text and not executed.
Does it look the same as GitHub?
Common syntax (headings, lists, tables, code, task lists) renders the same; GitHub-specific features such as @mentions, Mermaid diagrams and math are not supported.
How do I add a line break?
A single newline is merged into the same paragraph. End a line with two spaces or a backslash to force a break, or leave a blank line for a new paragraph.
