+### Scheduling
+Tasks can define the schedule that they run on and how their schedule is executed.
+To do this, define a method named `schedule` with an array formatted as:
+
+```ruby
+  [:schedule_type, duration]
+```
+
+For example, if you wanted your task to run every 5 minutes, you would do the
+following:
+
+```ruby
+#!/usr/bin/env ruby
+
+class MyService
+  class Tasks
+    class Quiz
+      def schedule
+        [:every, '5m']
+      end
+
+      def run!(args)
+        puts args
+        args
+      end
+    end
+  end
+end
+```
+
+This would execute the `run!` method every 5 minutes. Duration can be defined as a
+string in the `'<number>s/m/h/d/w'` format or as a number of seconds. Schedule types
+are `:in, :at, :every, :cron, :interval`. See rufus-scheduler's
+[README](https://github.com/jmettraux/rufus-scheduler#in-at-every-interval-cron)
+for more information.
+
+The default for tasks that don't explicitly define a schedule is
+
+```ruby
+def schedule
+  [:interval, options[:loop_sleep_time]]
+end
+```
 
 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
