+Tag Lists
+=========
+
+Bulk add and/or remove tags by uploading a CSV file of Airship users. For more
+information about the use of this endpoint, incluiding CSV file formatting requirements
+please see `the Airship Tag Lists API documentation 
+<https://docs.airship.com/api/ua/#tag-tag-lists>`__
+
+
+Create List
+-----------
+
+Add tags to your contacts by creating a list and uploading CSV file with user identifiers. 
+The body of the request contains the name, description, and optional metadata for the 
+list. After you define a list, you populate it with a call to the Upload Tag List method.
+
+.. code-block:: ruby
+
+    require 'urbanairship'
+    UA = Urbanairship
+    airship = UA::Client.new(key: 'app_key', secret: 'master_secret')
+    tags = {'tag_group_name': ['tag1', 'tag2']}
+
+    tag_list = UA::TagList.new(client: airship)
+    tag_list.name = 'ua_tags_list_name'
+    tag_list.create(description: 'description', extra: {'key': 'value'}, add: tags)
+
+
+Upload List
+-----------
+
+Upload a CSV that will set tag values on the specified channels or named users. See `the
+Airship API documentation <https://docs.airship.com/api/ua/#operation-api-tag-lists-list_name-csv-put>`__ for CSV formatting requirements. Set 
+the optional `gzip` parameter to `true` if your file is gzip compressed.
+
+.. code-block:: ruby
+
+    require 'urbanairship'
+    UA = Urbanairship
+    airship = UA::Client.new(key: 'app_key', secret: 'master_secret')
+
+    tag_list = UA::TagList.new(client: airship)
+    tag_list.name = 'ua_tags_list_name'
+    tag_list.upload(csv_file: 'file_content', gzip: true)
+
+
+Dowload List Errors
+-------------------
+
+During processing, after a list is uploaded, errors can occur. Depending on the type 
+of list processing, an error file may be created, showing a user exactly what went wrong.
+
+.. code-block:: ruby
+
+    require 'urbanairship'
+    UA = Urbanairship
+    airship = UA::Client.new(key: 'app_key', secret: 'master_secret')
+
+    tag_list = UA::TagList.new(client: airship)
+    error_csv = tag_list.errors
+
+
+Retrieve All Tag Lists
+----------------------
+
+Retrieve information about all tag lists. This call returns a list of metadata that 
+will not contain the actual lists of users.
+
+.. code-block:: ruby
+
+    require 'urbanairship'
+    UA = Urbanairship
+    airship = UA::Client.new(key: 'app_key', secret: 'master_secret')
+
+    tag_list = UA::TagList.new(client: airship)
+    list_response = tag_list.list
