Markdown is a plain text formatting system [originally developed by John Gruber](https://daringfireball.net/projects/markdown/). It has since been standardized into [CommonMark](https://commonmark.org/), which is what SilverBullet uses (with some extensions). If you’re not yet familiar with Markdown [here is a good guide to get you started](https://www.markdownguide.org/basic-syntax/). We mentioned markdown _extensions_, here are the ones currently supported: * [[Frontmatter]] * Double-bracketed wiki links: `[[link to page]]`, optionally with aliases `[[link to page|alias]]`. * Hashtags, e.g. `#mytag`. * Command link syntax: `{[Stats: Show]}` rendered into a clickable button {[Stats: Show]}. * [[Markdown/Code Widgets]] * [Tables](https://www.markdownguide.org/extended-syntax/#tables) * [Fenced code blocks](https://www.markdownguide.org/extended-syntax/#fenced-code-blocks) * [Task lists](https://www.markdownguide.org/extended-syntax/#task-lists) * [Highlight](https://www.markdownguide.org/extended-syntax/#highlight) * [Automatic URL linking](https://www.markdownguide.org/extended-syntax/#automatic-url-linking) * Custom markdown extensions provided by plugs
