 2. it will execute the exceeded jobs at the next period. For example, you restrict the email sending jobs to run 1000 times per day. If your system generates 1010 email sending jobs, only 1000 email sending jobs can be executed today, and the other 10 email sending jobs will be executed tomorrow.

-The job you wish to restrict should inherit from Resque::Plugins::RestrictionJob class and add restrict definition. Example:
+It is especially useful when a system has an email invitation resque job, because sending emails too frequentyly will be treated as a spam. What you should do for the InvitationJob is to inherit it from Resque::Plugins::RestrictionJob class and add restrict definition. Example:
 
-	class MyRestrictionJob < Resque::Plugins::RestrictionJob
-	  restrict :per_day => 1000, :per_hour => 1000, :per_300 => 30
+	class InvitationJob < Resque::Plugins::RestrictionJob
+	  restrict :per_day => 1000, :per_hour => 100, :per_300 => 30
 
 	  #rest of your class here
 	end
 
-MyRestrictionJob can be run 1000 times per day, 100 times per hour and 30 times per 300 seconds.
+That means the InvitationJob can not be executed more than 1000 times per day, 100 times per hour and 30 times per 300 seconds.
 
 The argument of restrict method is a hash, the key of the hash is a period time, including :per_minute, :per_hour, :per_day, :per_week, :per_month, :per_year, and you can also define any period like :per_300 means per 300 seconds. the value of the hash is the job execution limit number in a period.
