## Install

<InstallCommand command="npx hyperframes add hw-title" item="hw-title" />

That writes `compositions/hw-title.html`, plus 1 supporting file under `assets/fonts/`.

## Add it to your video

It runs for 6 seconds at 1920×1080. Paste this into your composition:

```html index.html theme={null}
<div
  data-composition-id="hw-title"
  data-composition-src="compositions/hw-title.html"
  data-start="0"
  data-duration="6"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>
```

Move it in time with `data-start`. Put it on a different timeline row with
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
