-## Routing
-
-`routing` is a wrapper for the actual handler function to define multiple routes and their corresponding handlers:
-
-```typescript
-import { createRoutes } from 'thirty/createRoutes';
-
-export const handler = compose(
-  eventType<APIGatewayProxyEvent>(),
-  inject({
-    userService: () => ({
-      /*...*/
-    }),
-  }),
-  parseJson(),
-)(
-  createRoutes(router => {
-    router.get('/users', ({ deps }) => {
-      return {
-        statusCode: 200,
-        body: JSON.stringify(deps.userService.getUsers()),
-      };
-    });
-
-    router.post('/users', async ({ deps, jsonBody }) => {
-      return {
-        statusCode: 201,
-        body: JSON.stringify(deps.userService.createUser(jsonBody)),
-      };
-    });
-
