# Installation
## Include the SDK
Add the following `
```
Once the script is loaded and ready, it dispatches an `exp-analytics-loaded` event on both the `document` and `window` objects. You can listen to this event to begin tracking analytics events.
```javascript theme={null}
document.addEventListener('exp-analytics-loaded', function() {
console.log('Experro Analytics SDK is ready!');
// Proceed with initialization or tracking
});
```
- Placing it in `` ensures tracking begins as soon as possible.
- If you’re concerned about page‑render performance, you can move it just before ``, but make sure your initialization code runs after the script has loaded.
## Prerequisites
Before initializing the SDK, you’ll need the following from the Experro admin panel:
* **Tenant ID** (`tenantId`)
Your unique identifier for billing and data partitioning.
* **Workspace ID** (`workspaceId`)
Choose or create a workspace to segment events by functional area.
* **Environment ID** (`environmentId`)
Use distinct values (e.g. `dev`, `staging`, `prod`) to isolate test data from production.
* **Channel ID** (`channelId`)
Typically `"web"`, but you can define custom channels (e.g. `"mobile-web"`, `"kiosk-app"`).
* **Language / Locale** (`language`)
A locale code (e.g. `"en-US"`, `"fr-FR"`) to help you segment by user region.
Make sure you have these five values handy in your application’s configuration before moving on to next step.
