TODO: this feels like it’s placed weirdly.
Where could it go?

If you’re getting errors from TypeScript related to imports with an `*.mdx`
extension, create an `mdx.d.ts` file in your types directory and include it
inside your `tsconfig.json`.

```tsx
// types/mdx.d.ts
declare module '*.mdx' {
  let MDXComponent: (props) => JSX.Element;
  export default MDXComponent;
}
```
