+# Help
+
+## Running the tests
+
+To run the test through DrRacket, simply open the test file and click the 'Run' button in the upper right.
+
+To run the test from the command line, run the test from the exercise directory with the following command:
+
+```
+raco test <exercise>-test.rkt
+```
+
+where `<exercise>` should be replaced with the exercise's slug.
+
+## Submitting your solution
+
+You can submit your solution using the `exercism submit leap.rkt` command.
+This command will upload your solution to the Exercism website and print the solution page's URL.
+
+It's possible to submit an incomplete solution which allows you to:
+
+- See how others have completed the exercise
+- Request help from a mentor
+
+## Need to get help?
+
+If you'd like help solving the exercise, check the following pages:
+
+- The [Racket track's documentation](https://exercism.org/docs/tracks/racket)
+- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
+- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
+
+Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
+
+To get help if you're having trouble, you can use one of the following resources:
+
+- [The Racket Reference](http://docs.racket-lang.org/reference/index.html)
+- [/r/racket](https://www.reddit.com/r/racket) is the Racket subreddit.
+- [StackOverflow](http://stackoverflow.com/questions/tagged/racket) can be used to search for your problem and see if it has been answered already. You can also ask and answer questions.

+# Leap
+
+Welcome to Leap on Exercism's Racket Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+Given a year, report if it is a leap year.
+
+The tricky thing here is that a leap year in the Gregorian calendar occurs:
+
+```text
+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.
+
+## Notes
+
+Though our exercise adopts some very simple rules, there is more to
+learn!
+
+For a delightful, four minute explanation of the whole leap year
+phenomenon, go watch [this youtube video][video].
