+# MISP Extended Events
+
+MISP can now extend an event (starting from version 2.4.90). This allows users to build full blown events that extend an existing event, giving way to a combined event view that includes a sum total of the event along with all extending events.

-# WIP
+# MISP modules
+
+MISP modules are autonomous modules that can be used for expansion and other services in MISP.
+The modules are written in Python 3 following a simple API interface. The objective is to ease the extensions of MISP functionalities without modifying core components. The API is available via a simple REST API which is independent from MISP installation or configuration.
+MISP modules support is included in MISP starting from version 2.4.28.
