Zettels may contain optional metadata in the YAML frontmatter.

## Date

The date of the zettels can be specified in the “date” metadata field (neuron new automatically fills in this field):

---
date: 2020-08-21T13:06
---


This date can be made to display in a query result by using the timeline flag (see Link Queries).

## Pinning

Zettels can be pinned in the z-index so that they appear at the top. To pin a zettel, add the “pinned” tag (see Tags) to it.

---
tags:
- pinned
---


## Hiding a zettel

Sometimes you want to “draft” a note, and as such wish to hide it from the rest of Zettelkasten, notably the z-index. This can be achieved by marking a zettel as “unlisted”:

---
unlisted: true
---


You can explicitly specify a title using the title metadata; otherwise, Neuron will infer it from the Markdown heading or Zettel ID.

The metadata key tags or keywords can be used to specify tags, although neuron supports inline tags as well (see Tags).
