+Feature: Insert new routes in Kapow! server.
+  Insert routes allow users to configure the server. New
+  routes could be inserted at the begining or before any
+  existing route of the routes list.
+
+  Background:
+    Given I have a Kapow! server whith the following routes:
+      | method | url_pattern        | entrypoint | command                                          |
+      | GET    | /listRootDir       | /bin/sh -c | ls -la / \| response /body                       |
+      | GET    | /listDir/{dirname} | /bin/sh -c | ls -la /request/params/dirname \| response /body |
+
+  Scenario: Insert a route at the beginning.
+    A route can be inserted at the begining of the list
+    by specifying an index 0 in the request.
+
+      When I insert the route:
+        | method | url_pattern  | entrypoint | command                    | index |
+        | GET    | /listRootDir | /bin/sh -c | ls -la / \| response /body |     0 |
+      Then I get ok as response code
+      And I get "OK" as response phrase
+      And I get the following entity as response body:
+        | method | url_pattern  | entrypoint | command                    | index | id |
+        | GET    | /listRootDir | /bin/sh -c | ls -la / \| response /body |     0 |  * |
+
+  Scenario: Insert a route in the middle.
+    A route can be inserted in the middle of the list
+    by specifying an index less or equal to the last
+    index in the request.
+
+      When I insert the route:
+        | method | url_pattern  | entrypoint | command                    | index |
+        | GET    | /listRootDir | /bin/sh -c | ls -la / \| response /body |     1 |
+      Then I get ok as response code
+      And I get "OK" as response phrase
+      And I get the following entity as response body:
+        | method | url_pattern  | entrypoint | command                    | index | id |
+        | GET    | /listRootDir | /bin/sh -c | ls -la / \| response /body |     1 |  * |
