+### How can I change the API Portal logo and favicon?
+
+:::info
+A `Swagger Aggregator v3.9.0` or above and an `API Portal v2.2.0` or above are required for this feature
+:::
+
+To customize the `API Portal` logo and favicon, you have to simply edit the Swagger Aggregator [configuration](/development_suite/api-console/advanced-section/swagger-aggregator/configuration.md) by adding at the first level the `apiPortalConfig` object, and setting the `logoUrl` and `faviconUrl`. You should write something like this:
+  ```
+  {
+    ...
+    "apiPortalConfig": {
+      "logoUrl": "/your-logo-url",
+      "faviconUrl": "/your-favicon-url"
+    },
+  }
+  ```

+### How can I change the prefix of API Portal endpoints?
+
+:::info
+A `Swagger Aggregator v3.9.0` or above and an `API Portal v2.2.0` or above are required for this feature
+:::
+
+By default, `API Portal` endpoints have the `/api` prefix but you can change it by:
+1. Set the custom prefix in the Swagger Aggregator [configuration](/development_suite/api-console/advanced-section/swagger-aggregator/configuration.md)
+```json
+{
+  ...
+  "apiPortalConfig": {
+    "apiPrefix": "/custom-prefix",
+  }
+}
+```
+2. Follow the [guide](/runtime_suite/api-portal/configuration#reroute-endpoints-on-a-custom-endpoint) on the API Portal
+
+### How can I add the global servers options in the API Portal?
+
+:::info
+A `Swagger Aggregator v3.9.0` or above and an `API Portal v2.2.0` or above are required for this feature
+:::
+
+To add the global servers options, you have to add them in the `baseSwagger` object of the Swagger Aggregator [configuration](/development_suite/api-console/advanced-section/swagger-aggregator/configuration.md).
+The `servers` list comes from [OpenApi 2.0](https://swagger.io/specification/v2/).
+
+You should write something like this:
+```json
+{
+  ...
+  "baseSwagger": {
+    "version": "2.0",
+    "servers:" [
+      {
+        "url": "http://your-first-server"
+      },
+      {
+        "url": "http://your-second-server",
+        "description": "A nice description"
+      }
+    ]
+  }
+}
+```
