 The extension will take care of reporting successful/failed payments and payment method changes
 to Churn Buster.
 
+### Failed installments retries
+
+The extension generates an installment for each subscription cycle, however some of them can fail
+(e.g. for an expired credit card). On each processor run the extension will try to complete all past
+failed installments, however this is not always the desired behaviour.
+
+If you want to process only the latest installment in each subscription, regardless of any number of
+failed installments prior to that, you can configure the extension like so:
+
+```ruby
+SolidusSubscriptions.configure do |config|
+  # ...
+
+  config.clear_past_installments = true
+end
+```
