+Beautify markdown.
+
+## Code
+
+```space-lua
+local prettier = js.import("https://cdn.jsdelivr.net/npm/prettier/standalone/+esm")
+local prettierMarkdown = js.import("https://cdn.jsdelivr.net/npm/prettier/plugins/markdown/+esm")
+
+function formatText(text)
+  return prettier.format(text, {
+    parser = "markdown",
+    plugins = { prettierMarkdown },
+
+    printWidth = 160,
+    proseWrap = "preserve",
+
+    -- These DO NOT affect markdown tables
+    useTabs = true,
+    tabWidth = 4,
+  })
+end
+
+function formatDocument()
+  local text = editor.getText()
+  local formattedText = formatText(text)
+  editor.setText(formattedText)
+end
+
+command.define {

+  run = formatDocument,
+}

+**Important Notes:**
+
+- **Placement:** `prettier-ignore` _must_ be the very first line within the code
+  fence. Any leading whitespace will cause it to be ignored.
+- **Scope:** `prettier-ignore` applies to the entire code fence it's placed in.
+- **Alternative:** If you want to disable formatting for a specific section of
+  code _within_ a code fence, you can use `prettier-ignore` on a single line:
