Normal sudoku rules apply and clues outside the grid give the sum of the first X digits seen in the row/column, given that X is the first digit seen from the clue. The grid must be filled with the 12 different pentominoes (allowing rotation/reflection), all of which cross a box boundary. Digits in shapes cannot repeat, and sum to an odd number for pentominoes, and an even number for tetrominoes. The three placed bar lines act as shape boundaries.
