 ## 1. How to use
+### 1.1. CLI
 Simply run program with following parameters:  
 `program reflector rotorLeft rotorCenter rotorRight staringPositions [plugboardCipher]`
 
 `reflector` - Value of reflector to be used [`B` or `C`]  
 `rotor`(Left, Right, Center) - Value of rotor to be used [`I`-`VIII`]. One rotor can not be connected to multiple places.  
 `startingPositions` - Staring positions of reflector, left, center and right rotor respectively. (4 character string with capital letters)  
 `plugboardCipher` - Cipher that represents plugboard connections. Contains exactly 26 non-repeatable capital letters. Every possition contains letter that represents connection with letter on coresponding position.  This argument is optional. If it is not passed, every letter will be connected to itself.
+### 1.2. GUI
+Just execute GUI version.
