+# Description
+TODO
+# How to use
+- Add a Node2D node named "StateMachine" with the script state_machine.gd
+- Initialize the states, initial state and conditions:
+{{{
+	$StateMachine.add_state("idle")
+	$StateMachine.add_state("hurt")
+	$StateMachine.add_state("dead")
+	$StateMachine.set_init_state("idle")
+	$StateMachine.add_transition("idle", "hurt", [], "fire")
+	$StateMachine.add_transition("hurt", "dead", ["has_stuff_been_handled", "is_dead"])
+	$StateMachine.add_transition("hurt", "idle", ["has_stuff_been_handled"])
+}}}
+
+- Trigger an event
+{{{
+	$StateMachine.trigger("fire")
+}}}
+
+- Add a condition: it's just a func returning a bool
+{{{
+    def has_stuff_been_handled():
+        return true
+}}}
+
+- Add callbacks for state entering/update/exiting: just add the state name in on_XXXXX_state_YYYY()
+{{{
+    func on_idle_state_enter():
+        pass
+
+    func on_idle_state_update(delta):
+        pass
+
+    func on_idle_state_exit():
+        pass
+}}}
+- Enabling debug mode (logs when changing states)
+{{{
+    $StateMachine.set_debug_enabled(true)
+}}}
+
+- Get the current state
+{{{
+    $StateMachine.get_current_state()
+}}}
+
+- Get the last known state (before the current one)
+{{{
+    $StateMachine.get_last_state()
+}}}
