Introduction to YAML Frontmatter

YAML frontmatter is a metadata block added at the beginning of a Markdown file. It is widely supported by many static site generators (such as Jekyll, Hugo) and note-taking applications (such as Obsidian, Logseq).

Format Example

After enabling YAML frontmatter, the exported Markdown file will contain metadata at the top in the following format:

---

uuid: abc123-def456-ghi789
model: pplx_pro
mode: copilot
