+Feature: Course Settings
+  As a course author, I want to be able to configure my course settings.
+
+  Scenario: User can set course dates
+    Given I have opened a new course in Studio
+    When I select Schedule and Details
+    And I set course dates
+    Then I see the set dates on refresh
+
+  Scenario: User can clear previously set course dates (except start date)
+    Given I have set course dates
+    And I clear all the dates except start
+    Then I see cleared dates on refresh
+
+  Scenario: User cannot clear the course start date
+    Given I have set course dates
+    And I clear the course start date
+    Then I receive a warning about course start date
+    And The previously set start date is shown on refresh
+
+  Scenario: User can correct the course start date warning
+    Given I have tried to clear the course start
+    And I have entered a new course start date
+    Then The warning about course start date goes away
+    And My new course start date is shown on refresh
