## Collect Statistics on the Use of Open Source

Vue Wrapper of TOAST UI Editor applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Editor is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. ui.toast.com) is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following `usageStatistics` options when declare Vue Wrapper component.

```js
const options = {
  ...
  usageStatistics: false
}
```

## 💾 Install

### Using npm
