Markdown uses plain text to mark headings, lists, emphasis and links. SilverBullet renders that formatting while you write, and keeps the source in ordinary .md files.

SilverBullet uses CommonMark with extensions such as page links, tags and expressions. Standard Markdown remains readable in other tools. Extensions may be shown as source or interpreted differently. Executable expressions require SilverBullet. All these extensions are optional.
