+# Utility Tools for the `xDEVS.rs` Simulator
+
+This crate contains a bunch of useful utilities to use in combination with the `xDEVS` simulator.
+
+## DEVS Model Tree Parsers
+
+It allows you to parse a DEVS model described using the DEVS Model Tree (DMT) notation.
+This is useful for other utilities to automatically adapt to different models.
+
+**You must enable the `dmt` feature if you want to use this utility.**
+
+## MQTT Handler for Real-Time Simulation
+
+This allows you to easily connect to an MQTT broker to send/receive events during a RT simulation.
+This is quite useful when developing Hardware-in-the-Loop (HIL) simulation or Digital Twins (DTs).
+
+**You must enable the `mqtt` feature if you want to use this utility.**
