 # SimpleStateMachineLibrary
 A C# library for realization simple state-machine
+
+Example:
+--------
+
+**Structure**
+```C#
+
+            StateMachine stateMachine = new StateMachine();
+            
+            State state1 = stateMachine.AddState("State1");
+            State state2 = stateMachine.AddState("State2");
+            State state3 = stateMachine.AddState("State3");
+            State state4 = stateMachine.AddState("State4");
+
+            Transition transition1 = state1.AddTransitionFromThis("Transition1", state2);
+            Transition transition2 = stateMachine.AddTransition("Transition2", state2, state3);
+            Transition transition3 = state4.AddTransitionToThis("Transition3", state3);
+
+            state1.SetAsStartState();
+            state1.OnExit(Method1);
+            state2.OnExit(Method2);
+            state3.OnExit(Method3);
+            state4.OnExit(Method4);
+```
+**Example methods**
+```C#
+        static void Method1(State state, Dictionary<string, object> parameters)
+        {
+            state.StateMachine.InvokeTransition("Transition1");
+        }
+        
+        static  void Method2(State state, Dictionary<string, object> parameters)
+        {
+            state.StateMachine.InvokeTransition("Transition2");
+        }
+        
+        static void Method3(State state, Dictionary<string, object> parameters)
+        {
+            state.StateMachine.InvokeTransition("Transition3");
+        }
+        
+        static void Method4(State state, Dictionary<string, object> parameters)
+        {
+
+        }
+```
