The brief
Normal (irregular) 6x6 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 6. Adjacent digits on the green line have a difference of at least 3. Digits on the marked diagonal do not repeat. Digits on an arrow sum to the digit in the circle from which the arrow emerges. Digits joined by a black dot have a 1:2 ratio. (Not all dots are given.)
