-recovery. In order to enable the integration, simply add your Churn Buster credentials to your
-configuration:
-
-```ruby
-SolidusSubscriptions.configure do |config|
-  # ...
-
-  config.churn_buster_account_id = 'YOUR_CHURN_BUSTER_ACCOUNT_ID'
-  config.churn_buster_api_key = 'YOUR_CHURN_BUSTER_API_KEY'
-end

-to Churn Buster.
