Hi,
There are 2 plugins:
The out of stock notification plugin which alerts you when products are out of stock (by default, once a day).
The order auto cancel plugin which cancels automatically created orders after a certain time.
Both plugins require that you first setup your cron task:

There is no documentation for these plugins because they basically don't have any options. Once they are published and that the cron task is setup they will do their thing automatically.
