For Optimizely Content Management System (CMS) 12 websites, you can set up tracking by installing a NuGet package.

## Prerequisites

- Have an active Content Recommendations subscription.
- Have an Optimizely CMS 12 website.
- Use `RenderRequiredClientResources` in the HTML `<head>`, as this is where the tracking script is injected.

## Install the NuGet package

### Add the Optimizely NuGet feed

1. Open Visual Studio.
2. Go to **Tools > NuGet Package Manager > Package Manager Settings**.
3. Select **Package Manager > Package Sources** and click the **Add** (+) icon.
4. Enter a **Name** (e.g., `Optimizely`) and the **Source** URL `https://nuget.optimizely.com/feed/packages.svc/`.
5. Click **OK**.

### Install the Package

1. Go to **Solution Explorer**.
2. Select **Dependencies** from **Manage NuGet Packages** drop-down list.
3. Select the **Optimizely** package source.
4. Browse for `EPiServer.Personalization.Content.UI` and click **Install**.
5. Rebuild your solution.

## Configure tracking in `appsettings.json`

Add the following configuration block to the `EPiServer` section of your `appsettings.json` file. Populate the values with the credentials from your account:

```json
{
  "EPiServer": {
    "ContentPersonalization": {
      "Environment": "your-region.idio.episerver.net",
      "ClientName": "your-client-name",
      "ClientId": "YOUR_CLIENT_ID",
      "ApiToken": "YOUR_API_TOKEN",
      "DisableDefaultTracking": false
    }
  }
}
```

- `Environment` – The environment endpoint for your account.
- `ClientName` – The friendly name of your client account.
- `ClientId` – The alphanumeric client identifier for your account.
- `ApiToken` – The token used to authenticate to the API endpoint.
- `DisableDefaultTracking` – (Optional) Used to disable the default tracking script if you use another method like Google Tag Manager. Set to `true` to prevent duplicate tracking.

## Deploy and validate

Deploy your updated application. To validate the installation, open your website, launch your browser's Developer Tools, and check the **Network** tab to confirm that requests are being sent to the Content Recommendations service (for example, filter for `idio`).
