# 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. --- ## Sections (load on demand) - `references/the-default-usually-good-enough.md` — The default — usually good enough - `references/shape-of-a-static-markdown-template.md` — Shape of a `static markdown` template - `references/essential-helper-markdownescape.md` — Essential helper: `markdownEscape` - `references/the-markdown-helpers-toolkit.md` — The `markdown-helpers` toolkit - `references/delegation-composes.md` — Delegation composes - `references/pitfalls.md` — Pitfalls - `references/worked-example-note-card-with-custom-markdown.md` — Worked example: `Note` card with custom markdown - `references/rendering-markdown-html-at-runtime.md` — Rendering markdown → HTML at runtime - `references/when-youre-done.md` — When you're done
