+## Route Options
 
-- It will work with single objects and arrays. `pathToSource` is optional field,

+| pathToSource | Lens<object, object \| object[]> | Path to the nested object, this should be `R.lensPath(['somepath', '...'])` |
 
-- Improvements todo
-- Change the options structure to following, which will allow using multiple paths
+The options for the Route config can also be array, the type is represented as
 
-```js
-const options = {
-  sources: [
+```ts
+interface RouteOptions {
+  lenses: Lens<object, string>[];
+  pathToSource?: Lens<object, Response>;
+}
+
+// allows single option object or multiple
+const routeOptions: RouteOptions | RouteOptions[];

+
+```ts
+const responseObject = {

+  projects: [
