+# Hierarchical Finite State Machine
+
+This example shows how to apply the State machine programming
+pattern in GDscript, including Hierarchical States, and a
+pushdown automaton.
+
+Language: GDScript
+
+Renderer: GLES 2
+
+## Why use a state machine
+
+States are common in games. You can use the pattern to:
+
+1. Separate each behavior and transitions between behaviors,
+   thus make scripts shorter and easier to manage.
+
+2. Respect the Single Responsibility Principle.
+   Each State object represents one action.
+
+3. Improve your code's structure. Look at the scene tree and
+   FileSystem tab: without looking at the code, you'll know
+   what the Player can or cannot do.
+
+You can read more about States in the excellent
+[Game Programming Patterns ebook](https://gameprogrammingpatterns.com/state.html).
