+Feature: Collections Directory
+  As a hacker who likes to structure content without clutter
+  I want to be able to organize my collections under a single directory
+  And render them from there
+
+  Scenario: Custom collections_dir containing only posts
+    And I have a collections/_posts directory
+    And I have the following post within the "collections" directory:
+      | title         | date       | content         |
+      | Gathered Post | 2009-03-27 | Random Content. |
+    And I have a "_config.yml" file with content:
+    """
+    collections_dir: collections
+    """
+    When I run jekyll build
+    Then I should get a zero exit status
+    And the _site directory should exist
+    And I should see "Random Content." in "_site/2009/03/27/gathered-post.html"
+
+  Scenario: Rendered collection in custom collections_dir also containing posts
+    Given I have a collections/_puppies directory
+    And I have the following document under the "puppies" collection within the "collections" directory:
+      | title  | date       | content            |
