 the format of that meta string is, so it defaults to how markdown handles it:
 `meta` is ignored.
 
-But what if you want to access `meta`?
-The short answer is: use [`remark-mdx-code-meta`][remark-mdx-code-meta].
+But what if you want to access `meta` at runtime?
+That’s exactly what the remark plugin
+[`remark-mdx-code-meta`][remark-mdx-code-meta] does.
 It lets you type JSX attributes in the `meta` part which you can access by
 with a component for `pre`.
 
-The long answer is: do it yourself, however you want, by writing a custom plugin
-to interpret the `meta` field.
-For example, it’s possible to pass that string as a prop with a rehype plugin:
-
-```tsx path="rehype-meta-as-attributes.js"
-import {visit} from 'unist-util-visit'
-
-function rehypeMetaAsAttributes() {
-  /**
-   * @param {import('hast').Root} tree
-   *   Tree.
-   */
-  return function (tree) {
-    visit(tree, 'element', function (node) {
-      if (node.tagName === 'code' && node.data && node.data.meta) {
-        node.properties.meta = node.data.meta
-      }
-    })
-  }
-}
-```
-
-This would yields the following JSX:
-
-```tsx path="output.jsx"
-<>
-  <pre>
-    <code className="language-js" meta='filename="index.js"'>
-      console.log(1)
-    </code>
-  </pre>
-</>
-```
-
-<Note type="important">
-  **Important**: the `meta` attribute is not valid on `code` elements in HTML.
-  Please make sure to handle it with a `code` component.
-</Note>
-
-The meta string in this example looks a lot like HTML attributes.
-What if we wanted to add each “attribute” as a prop?
-That can be achieved with the same rehype plugin as above with a different
-`onelement` handler:
-
-```tsx path="rehype-meta-as-attributes.js"
-// A regex that looks for a simplified attribute name, optionally followed
-// by a double, single, or unquoted attribute value
-const re = /\b([-\w]+)(?:=(?:"([^"]*)"|'([^']*)'|([^"'\s]+)))?/g
-
-    // …
-    visit(tree, 'element', function (node) {
-      let match
-
-      if (node.tagName === 'code' && node.data && node.data.meta) {
-        re.lastIndex = 0 // Reset regex.
-
-        while ((match = re.exec(node.data.meta))) {
-          node.properties[match[1]] = match[2] || match[3] || match[4] || ''
-        }
-      }
-    })
-    // …
-```
