+# This script demonstrates how to use the Tableau Server Client
+# to publish a datasource to a Tableau server. It will publish
+# a specified datasource to the 'default' project of the provided site.
+#
+# Some optional arguments are provided to demonstrate async publishing,
+# as well as providing connection credentials when publishing. If the
+# provided datasource file is over 64MB in size, TSC will automatically
+# publish the datasource using the chunking method.
+#
+# For more information, refer to the documentations:
+# (https://help.tableau.com/current/api/rest_api/en-us/REST/rest_api_ref_datasources.htm#publish_data_source)
+#
+# For signing into server, this script uses personal access tokens. For
+# more information on personal access tokens, refer to the documentations:
+# (https://help.tableau.com/current/server/en-us/security_personal_access_tokens.htm)
+#
+# To run the script, you must have installed Python 3.5 or later.
