# Particle Text · Pro

Text sampled into canvas particles that fly in from random positions to form the letters, then scatter from the pointer and spring back.

This is a Charcoal UI Pro component. Its source and examples are available with a Pro seat: https://charcoalui.com/pricing

## With a Pro seat

1. Add the registry to components.json:

```json
{
  "registries": {

      "headers": {
        "Authorization": "Bearer ${CHARCOAL_LICENSE_KEY}"
      }
    }
  }
}
```

2. Copy your licence key from https://charcoalui.com/dashboard and put it in .env.local as CHARCOAL_LICENSE_KEY, then:

```bash
npx shadcn@latest add @charcoal/particle-text
```

To read Pro source through this MCP server, reconnect it with the header "Authorization: Bearer <licence key>".
