+
+## Running the tests
+
+For running the tests provided, you will need the Minitest gem. Open a
+terminal window and run the following command to install minitest:
+
+```
+gem install minitest
+```
+
+
+Run the tests from the exercise directory using the following command:
+
+```
+ruby <snake-case-exercise>_test.rb
+```
+
+Please replace `<snake-case-exercise>` with your exercise name in snake_case.
+
+## Color output
+
+You can `require 'minitest/pride'` or run the following command to get colored output:
+
+```
+ruby -r minitest/pride <snake-case-exercise>_test.rb
+```
+
+## Submitting your solution
+

+# Allergies
+
+Welcome to Allergies on Exercism's Ruby Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.
+
+An allergy test produces a single numeric score which contains the information about all the allergies the person has (that they were tested for).
+
+The list of items (and their value) that were tested are:
+
+- eggs (1)
+- peanuts (2)
+- shellfish (4)
+- strawberries (8)
+- tomatoes (16)
+- chocolate (32)
+- pollen (64)
+- cats (128)
+
+So if Tom is allergic to peanuts and chocolate, he gets a score of 34.
+
+Now, given just that score of 34, your program should be able to say:
+
+- Whether Tom is allergic to any one of those allergens listed above.
+- All the allergens Tom is allergic to.
+
+Note: a given score may include allergens **not** listed above (i.e.  allergens that score 256, 512, 1024, etc.).
+Your program should ignore those components of the score.
+For example, if the allergy score is 257, your program should only report the eggs (1) allergy.
