+## Agent-Specific Real-Time Translation
+
+To support agent-specific real-time translation in Omnichannel for Customer Service, a new field must be added to the `systemuser` entity within the Dataverse. This field will store the ISO 639-1 language code representing the agent's preferred language. The language code should be a two-letter code (e.g., 'de' for German, 'es' for Spanish, etc.).
+
+To enable and configure agent-specific real-time translation, follow these steps:
+
+1. Add a custom field to the `systemuser` entity in the Dataverse to store the ISO 639-1 language code for each agent's preferred language (e.g., 'en' for English, 'de' for German).
+
+2. In the script, locate the `C1WebResourceNamespace` object and find the `agentPreferredLanguageField` property. Replace `'jkalz_preferredlanguagecode'` with the actual schema name of the custom field you added in step 1. This should be a string in single quotes.
+
+3. Set the `enableAgentSpecificTranslation` property to `true` to activate the agent-specific translation feature.
+
+Example configuration in the script:
+```javascript
+var C1WebResourceNamespace = {
+    // ... (other properties)
+
+    // The actual schema name of the custom field for agent's preferred language
+    agentPreferredLanguageField: 'your_custom_field_name_here',
+
+    // Enable agent-specific translations
+    enableAgentSpecificTranslation: true,
+
+    // ... (rest of the script)
+};
+```
+
+After configuring these values, the script will use the preferred language settings from each agent's profile to perform translations during customer interactions.
