## Install
```bash Terminal
npx hyperframes add lt-stack-bars
```
That writes one file: `compositions/lt-stack-bars.html`.
## Add it to your video
It runs for 4.8 seconds at 1920×1080. Paste this into your composition:
```html index.html
```
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.
## Add it to a project
### Ask your agent
```text
Add the Lower Third — Stack Bars block from the HyperFrames Catalog to this project.
Replace the demo content with mine and match the existing design and timing.
```
### Install from the terminal
```bash
npx hyperframes add lt-stack-bars
```
## Use it
Ask your agent to replace the example content, match the project style, and place the block at the right moment in the video.
**Wiring it by hand.** The installed block can be added to a host composition with:
```html
```
