please help!! Moore diagram

A Universal Serial Bus (USB) communication link requires a circuit that produces the sequence 00000001. You are to design a synchronous sequential circuit that starts producing this sequence for input  E=1. Once the sequence starts, it completes. If  E=1, during the last output in the sequence, the sequence repeats. Otherwise, if  E=0, the output remains constant at 1.

a. Draw the Moore state diagram for the circuit.

b. Find the state table and make a state assignment.

c. Design the circuit using D flip-flops and logic gates. A reset should be included to place the circuit in the appropriate initial state at which  E  is examined to determine if the sequence of constant 1s is to be produced.

 

If someone could just help me with the Moore diagram I could deduce the rest from there.
