# Obsidian Flavored Markdown
[[Obsidian]] parses CommonMark plus GitHub Flavored Markdown (tables, task lists, strikethrough, autolinks), and adds its own extensions on top. Knowing which is which matters the moment your notes leave Obsidian: standard [[Markdown]] travels everywhere, the extensions don't.
## Obsidian-specific extensions
| Syntax | Feature |
| --- | --- |
| `[[Note]]`, `[[Note#Heading]]`, `[[Note#^block]]` | [[Obsidian Wikilinks]] |
| `![[Note]]` | [[Obsidian Embeds]] |
| `^block-id` | [[Block references]] |
| `> [!note]` | [[Obsidian Callouts]] |
| `%% hidden %%` | Comments, invisible in Reading view |
| `==text==` | Highlight |
| `#tag`, `#nested/tag` | [[Obsidian Tags]] |
| `---` block at the top | [[Obsidian Properties\|Properties]] (YAML frontmatter) |
| ` ```mermaid ` | [[Mermaid]] diagrams |
| ` ```query ` | Embedded [[Obsidian Search]] results |
| `$...
and `$...$` | Math via MathJax/LaTeX |
| `[^1]` and `^[inline]` | [[Obsidian Footnotes]] |
## Good to know
- Frontmatter, comments, highlights, and footnotes are shared with other Markdown dialects; wikilinks, embeds, callouts, and block IDs are the truly Obsidian-flavored parts.
- Publishing pipelines (like mine to Ghost) must convert or strip the extensions; that conversion step is where most "why does my post look broken" issues come from.
- Obsidian can write standard Markdown links instead of wikilinks if portability is a priority (see [[Obsidian Wikilinks]]).
