+# Leap
+
+Write a program that will take a year and report if it is a leap year.
+
+The tricky thing here is that a leap year occurs:
+
+```plain
+on every year that is evenly divisible by 4
+  except every year that is evenly divisible by 100
+    unless the year is also evenly divisible by 400
+```
+
+For example, 1997 is not a leap year, but 1996 is.  1900 is not a leap
+year, but 2000 is.
+
+If your language provides a method in the standard library that does
+this look-up, pretend it doesn't exist and implement it yourself.
+
+## Notes
+
+For a delightful, four minute explanation of the whole leap year
+phenomenon, go watch [this youtube video][video].

+### Submitting Exercises
+
+Note that, when trying to submit an exercise, make sure you're exercise file you're submitting is in the `exercism/csharp/<exerciseName>` directory.
+
+For example, if you're submitting `bob.cs` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/csharp/bob/bob.cs`.
