Are there any rules on number of uses of each integer or using the same integer per row/column?

My answer:
Not sure how to format this, but from left to right, then top to bottom, the numbers would be:
2, 5, 5, 1
5, 1, 3, 2
2, 3, 3, 5
5, 1, 2, 4

Welcome to PuzzlingSE! Please include your answer in your post, and don't just link to it. This keeps it available, should you ever decide to delete the file and it does not force other people to download a file from an unknown person/source.

This was fun!
For my solution, I started in the four corners and worked my way inwards, ignoring the 1-5 constraint. When I had completed the grid without constraints, I again started in the corners to adjust numbers to fit the constraints until all constraints were satisfied.
-3- -4- -4- -1-
13 14 11
-1- -5- -1- -5-
11 10 13
-3- -2- -2- -5-
11 9 14
-5- -1- -4- -3-

Given the multiple possible answers, it is possible to add further restrictions, such as using integers from [2, 5] only (this solution qualifies!)
