# Markdown Format Authoring

_Authoring `static markdown` templates: defaults, markdownEscape, markdown-helpers toolkit, delegation, and pitfalls._

Boxel has a sixth display format alongside `isolated`, `embedded`, `fitted`, `atom`, and `edit`:

- **`markdown`** — the card (or field, or file) rendered as text in **Boxel Flavored Markdown** (BFM).

This format is what the realm serves under `Accept: text/markdown`, what "Copy as Markdown" puts on the clipboard, what the code-mode markdown preview panel shows, and what gets indexed into the `boxel_index.markdown` column. See the `boxel-flavored-markdown` skill for the dialect itself.

## Pair with

- **`boxel-flavored-markdown`** — for the dialect rules your output must conform to (directives, fenced renderers, escaping).
- **`boxel`** — for the surrounding CardDef structure and `<@fields.x />` delegation rules.

## Don't use for

- Rendering markdown into HTML at runtime in `isolated` or `embedded` (that's a runtime concern handled by Boxel's markdown component).
- Authoring rich content that lives in a `MarkdownField` instance — that's content, not a template.
