+=====================
+Contract Auto Payment
+=====================
+
+This module allows for the configuration of automatic payments on invoices that are created by a contract.
+
+Usage
+=====
+
+Enable Automatic Payment
+------------------------
+
+* Navigate to a customer contract
+* Check the `Auto Pay?` box to enable automatic payment
+* Configure the options as desired
+* Set the `Payment Token` to the payment token that should be used for automatic payment
+
+Automatic Payment Settings
+--------------------------
+
+The following settings are available at both the contract and contract template level:
+
+| Name | Description |
+|------|-------------|
+| Invoice Message | Message template that is used to send invoices to customers upon creation. |
+| Payment Retry Message | Message template that is used to alert a customer that their automatic payment failed for some reason and will be retried. |
+| Payment Fail Message | Message template that is used to alert a customer that their automatic payment failed and will no longer be retried. |
+| Auto Pay Retries | Amount of times to attempt an automatic payment before discontinuing and removing the payment token from the contract/account payment method. |
+| Auto Pay Retry Hours | Amount of hours that should lapse until retrying failed payments. |
+
+Payment Token
+-------------
+
+A valid payment token is required to use this module. These tokens are typically created during the `website_sale` checkout process, but they can also be created manually at the acquirer.
+
+A payment token can be defined in one of two areas:
+
+* Contract - Defining a payment token in the contract will allow for the use of this token for automatic payments on this contract only.
+* Partner - Defining a payment token in the partner will allow for the use of this token for automatic payments on all contracts for this partner that do not have a payment token defined.
