+### Experiment Hooks
+
+You can assign a proc that will be called when an experiment is reset or deleted. You can use these hooks to call methods within your application to keep data related to experiments in sync with Split.
+
+For example:
+
+``` ruby
+Split.configure do |config|
+  config.on_experiment_reset  = proc{ |experiment| # Do something on reset }
+  config.on_experiment_delete = proc{ |experiment| # Do something else on delete }
+end
+```
+
