• Brief description: https://help.obsidian.md/Editing+and+formatting/Obsidian+Flavored+Markdown
• Basic syntax list: https://help.obsidian.md/Editing+and+formatting/Basic+formatting+syntax

Unfortunately, Obsidian does not publish a formal spec for the OFM. Users should be aware Macana’s OFM parser is not guaranteed to be 100% compatible with Obsidian’s one, as the spec is not defined and even Obsidian behave inconsistent in some area.
