+### ExtensionConfig
+
+`extensionConfig` should be initialized under the specific extension rather than being defined in the root configuration. This allows for more granular configuration tailored to each extension's needs.
+
+For instance, to configure the dependencies plugin, you would initialize it as follows:
+
+```js
+const appInsights = new ApplicationInsights({
+    config: {
+        connectionString: 'InstrumentationKey=YOUR_INSTRUMENTATION_KEY_GOES_HERE',
+        extensionConfig: {
+            [DependenciesPlugin.identifier]: {
+                ignoreHeaders: []
+            }
+        }
+    }
+});
+```
