# Connect your product data

> Send product usage data to Bigdelta — from basic page views to advanced entitlement tracking.

Product data tells Bigdelta how your customers are actually using your product. This is a progressive setup — the more data you send, the more features you unlock.

### Install the SDK

The simplest starting point. Install the Bigdelta SDK and start capturing page views and form submissions automatically.

**What you need to provide:**

* Your Bigdelta tracking key (found in **Settings → [Access Keys](https://eu.bigdelta.com/access-keys)**)

**Install the package:**

<CodeGroup>
  ```bash browser theme={null}
  <script type="application/javascript" src="https://cdn.jsdelivr.net/npm/@bigdelta/bigdelta-browser/dist/index.iife.min.js"></script>
  ```

  ```bash npm theme={null}
  npm install @bigdelta/bigdelta-browser
  ```

  ```bash yarn theme={null}
  yarn add @bigdelta/bigdelta-browser
  ```
</CodeGroup>

**Initialize the client:**

```javascript theme={null}
import { Bigdelta } from '@bigdelta/bigdelta-browser';

const client = new Bigdelta({
  trackingKey: '<TRACKING_KEY>',
  defaultTrackingConfig: {
    pageViews: { enabled: true, singlePageAppTracking: 'any' }
  }
});
```

**What you unlock:**

* Basic product usage tracking (page views)
* **[Product Usage activities](/guide/features/activities)** — Product Usage Dropped and Product Usage Increased are generated weekly per account
