 ## Identify
 
 If you're not familiar with the Segment Specs, take a look to understand what the [Identify method](/docs/connections/spec/identify/) does. An example call would look like this:
 
-    analytics.identify({
-      userId: '019mr8mf4r',
-      traits: {
-        name: 'Kamala Khan',
-        email: '[email protected]',
-      }
-    });
+```js
+  analytics.identify({
+    userId: '019mr8mf4r',
+    traits: {
+      name: 'Kamala Khan',
+      email: '[email protected]',
+    }
+  });
+```
 
 You can use the Identify call to create or update customers in your Help Scout account.
