Decks¶

Cards are organized into decks for focused study sessions.

Deck Assignment¶

Deck assignment follows this priority (highest to lowest):

1. deck: in fence metadata — Per-card override
2. osmosis-deck: in frontmatter — Per-note override
3. Folder path — The note's folder becomes the deck name

Per-Card¶

```osmosis
deck: languages/french

Bonjour
***
Hello
```

Per-Note¶

---
osmosis-cards: true
osmosis-deck: languages/french
---

By Folder¶

A note at Vault/Languages/French/greetings.md automatically belongs to the Languages/French deck.

Hierarchical Decks¶

Decks are hierarchical, separated by /. For example:

languages/
  languages/french
  languages/spanish
  languages/japanese

The Dashboard shows this as a collapsible tree. You can study:

• A single deck — Just the cards directly in that deck
• A parent deck — The deck and all its sub-decks
• All decks — Every card across the vault

Automatic Inclusion¶

Instead of adding osmosis-cards: true to every note, you can auto-include notes by folder or tag in Settings > Osmosis:

• Include folders — Any note in these folders generates cards
• Include tags — Any note with these tags generates cards

This pairs well with folder-based deck assignment — add a folder to the include list, and every note in it automatically generates cards organized into the right deck.
