+Taskwarrior Shift All Recurrence Attributes Hook
+------------------------------------------------
+
+This is a hook for TaskWarrior (http://www.taskwarrior.org),
+which allow your recurrent tasks to inherit ``wait``, ``scheduled``
+and ``until`` attributes from the parent.
+
+Install
+-------
+
+Note: This hook has been rewritten to leverage taskpirate, for greater hook efficiency.
+Please see https://github.com/tbabej/taskpirate for instructions. Don't worry, it's straightforward.
+
+```
+git clone https://github.com/tbabej/taskwarrior-shift-all-recurrence-hook.git
+cp taskwarrior-shift-all-recurrence-hook/on-* ~/.task/hooks/
+```
+
+This hook leverages tasklib, so you need to install that too:
+
+```
+pip install tasklib
+```
+
+Use case
+--------
+
+Consider you have a periodic task, which is valid only for the certain day,
+e.g. on every Sunday you go running.
+
+```
+$ task add due:sunday recur:weekly
+```
+
+However, TaskWarrior will display the task right away, and you want to
+showing up only during the weekend, so that it does not distract your task
+list during the work week.
+
+If you try to add the recurrence again, this time with ``wait`` attribute,
+to hide the task until it is not relevant for you:
+
+```
+$ task add due:sunday recur:weekly wait:saturday
+```
+
+You will find out that TaskWarrior does not let tasks generated by this
+recurrence inherit the ``wait`` attribute, in the same manner as it does
+with the ``due`` attribute.
+
+This hook solves that.
