YAML Frontmatter

Zettel Notes supports YAML frontmatter for note properties. The frontmatter must be the first thing in the note, enclosed by --- lines. For example, this sets the title to Note Title:

---
title: Note Title
---

This is body of the note.

The following properties are supported:

1. title – The title of the note.
2. tag(s) or keywords – One or more tags associated with the note. keywords is read for compatibility with Zettlr v3.0.2.
3. author(s) – The author(s) of the note.
4. source or url – The original source or URL reference.
5. bookmark, pin, or star – Used to mark important notes.
6. id or uid – Must match the repository's UID regex.
7. date – At least 6 digits, typically in the format yyyyMMddHHmmss.

To specify multiple sources for a note, use array format. eg.

---
source:
      - https://google.com
      - https://gmail.com
---
