Margin Sudoku (Fun With Sudoku #26)

This Margin Sudoku puzzle was part of the World Sudoku Championship 2009 (Puzzle M2). This type appeared in the Semifinal of the championship. This puzzle was created for the Indian Team practice. Hopefully, this helped in team practice as 3 Indians were in the semi-final in the year 2009 World Sudoku Championship. I enjoyed a lot while creating this puzzle. Hopefully solving it will be equally enjoyable.
I am publishing this Margin Sudoku as 26th Sudoku in the Fun With Sudoku Series. Can you solve this Margin Sudoku puzzle?

Last week on 21st November 2014, we conducted a school round of Sudoku Champs 2015 in Delhi Public School North Bangalore. It was nice to see more than 100 kids solving Sudoku. Some of the top solvers in this competition are really good and hope that some of them will make it to the Indian Junior Sudoku team.

Rules of Margin Sudoku

Fill in the grid so that every row, every column, both diagonals, and the center 3x3 box contains all digits 1 through 9. The numbers outside the grid indicate that the given number is located in the first or second cell from the margin.
