+# Raindrops
+
+Welcome to Raindrops on Exercism's Julia Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Introduction
+
+Raindrops is a slightly more complex version of the FizzBuzz challenge, a classic interview question.
+
+## Instructions
+
+Your task is to convert a number into its corresponding raindrop sounds.
+
+If a given number:
+
+- is divisible by 3, add "Pling" to the result.
+- is divisible by 5, add "Plang" to the result.
+- is divisible by 7, add "Plong" to the result.
+- **is not** divisible by 3, 5, or 7, the result should be the number as a string.
+
+## Examples
+
+- 28 is divisible by 7, but not 3 or 5, so the result would be `"Plong"`.
+- 30 is divisible by 3 and 5, but not 7, so the result would be `"PlingPlang"`.
+- 34 is not divisible by 3, 5, or 7, so the result would be `"34"`.
+
+~~~~exercism/note
+A common way to test if one number is evenly divisible by another is to compare the [remainder][remainder] or [modulus][modulo] to zero.
+Most languages provide operators or functions for one (or both) of these.
