+Triggers
+========
+
+Sometimes we have to execute some script in reaction to an event.
+
+In the **data/triggers** we have a series of directories; scripts inside of them will be executed when the related action was performed on the GUI or calling the controller.
+
+Available triggers:
+- **update_person_in_event**: executed every time a person data in a given event is updated.
+- **attends**: executed only when a person is marked as attending an event.
+
+update_person_in_event and attends will receive these information:
+- via *environment*:
+  - NAME
+  - SURNAME
+  - EMAIL
+  - COMPANY
+  - JOB
+  - PERSON_ID
+  - EVENT_ID
+  - EVENT_TITLE
+- via stdin, a dictionary containing:
+  - dictionary **old** with the old data of the person
+  - dictionary **new** with the new data of the person
+  - dictionary **event** with the event information
+  - boolean **merged**, true if the data was updated
+
+In the **data/triggers-available** there is an example of script: **echo.py**.
