+# Script to be used with vault_password_file or --vault-password-file
+# to retrieve the vault password via your OSes native keyring application
+#
+# This script requires the ``keyring`` python module
+#
+# Add a [vault] section to your ansible.cfg file,
+# the only option is 'username'. Example:
+#
+# [vault]
+# username = 'ansible_vault'
+#
+# Additionally, it would be a good idea to configure vault_password_file in
+# ansible.cfg
+#
+# [defaults]
+# ...
+# vault_password_file = /path/to/vault-keyring.py
+# ...
+#
+# To set your password: python /path/to/vault-keyring.py set
+#
+# If you choose to not configure the path to vault_password_file in ansible.cfg
+# your ansible-playbook command may look like:
+#
+# ansible-playbook --vault-password-file=/path/to/vault-keyring.py site.yml
