+By default, the `insightConfig` in `package.json` is:
+
+```json
+  "insightConfig": {
+    "apiPrefix": "insight-api",
+    "routePrefix": "insight"
+  }
 ```
-$ grunt compile
+
+To change these routes, first make your changes to `package.json`, for example:
+
+```json
+  "insightConfig": {
+    "apiPrefix": "api",
+    "routePrefix": ""
+  }
 ```
 
-There is a convenient Gruntfile.js for automation during editing the code
