Need help with my next project

Hi Dear Friens,
Please i need some help with my next project, in this project i am trying to use an arduino mega 2560 + lcd 16x2 + rotary encoder with 2 stepper Motor + 2 bush button
the hole idea is to create a menu wish will contain a few option on it and if i acces to one of this option it will make me adjust the rotation of the stepper motor

What do you need help with? Have you written on paper the words you want to display on the LCD? DO you have the LCD connected and working? Please describe how you intend to power the project and include a block diagram showing the connections.
