+## What is a Turing Machine?
+https://en.wikipedia.org/wiki/Turing_machine
+
+## How to use
+(1) Create a new touring mashine
+```rust
+let turing_machine: TuringMachine = TuringMachine::new();
+```
+
+(2) Configure the belt
+```rust
+turing_machine.set_belt(index: usize, value: Value);
+```
+
+(3) Configure the state machine
+ (3.1) Set the transitions
+```rust
+turing_machine.set_transition(state: u64, trigger: Value, next_state: u64);
+```
+
+ (3.1) Set the actions
+```rust
+turing_machine.set_action(state: u64, trigger: Value, action: Action);
+```
+
+(4) Run the machine
+```rust
+turing_machine.start();
+```
