+# Periodic summaries - Visualize summaries of MISP data
+
+As of version 2.4.162, MISP includes a **periodic summary** feature allowing users to consult a summary based on a requested timeframe for data the user has access to.
+
+Currently, the summaries can be generated for 3 differents perdiods: `daily`, `weekly` and `monthly` and then sent to all users that subscribed one of these periods.
+
+In addition to choose which period users want to subscribed to, they can also specify filtering options such as tags or distribution level to be used to generate the summary.

+
+## Viewing summaries
+There are currently two ways to view a periodic summary:
+- In the MISP ui, click on the `View periodic summary` link when browsing events
+- Subscribe to one of the available period and receive the summary directly in the user's mailbox
+
+## Automatic delivery
+In order to have MISP send periodic mails, the periodic notification task should be scheduled. One of the easiest way to schedule recurring task is to use CRON jobs.
+
+For example, this entry could be added
+```text
+0 6 * * * /var/www/MISP/app/Console/cake Server sendPeriodicSummaryToUsers >/dev/null 2>&1
+```
+
+The `sendPeriodicSummaryToUsers` should be called daily and takes care of sending the summary to every users that subscribed to the `daily` notification. For the `weekly` and `monthly`, they will be sent on Mondays and on the first day of the month respectively.
+
+More details about setting the scheduled task and the CLI tool can be found in the *automation page* (/events/automation).
+
+
+## Extending / Overriding
+
+Site administrators of MISP can also extend, replace or remove parts of each periodic summary. 
+The notification templates can be found under the `app/View/Emails/html` folder. Each template extend a parametrized common template allowing site-admins to customize the summary to fit theirs needs.
+For example, the default `monthly` notification template is configured to only include a subset of the *detailed summary*.
+Options and developer documentation can be found in the `notification_common.ctp` file.
