Hi.  👋🏽  👋  **We are happy you are here.**  🎉 🌟







**`exercism/Crystal`** is one of many programming language tracks on [exercism(dot)org][exercism-website].

This repo holds all the instructions, tests, code, & support files for Crystal _exercises_ currently under development or implemented & available for students.



🌟   Track tooling (_test-runner, representer, analyzer, and Continuous Integration_) runs on Crystal `1.11.2`. 


🌟   Most exercises are solvable with Crystal `1.0.0` or higher.



This track is made up of **Practice Exercises**. Practice exercises are open-ended, and can be used to practice concepts learned, try out new techniques, and play.



















🌟🌟  Please take a moment to read our [Code of Conduct][exercism-code-of-conduct] 🌟🌟   

It might also be helpful to look at [Being a Good Community Member][being-a-good-community-member] & [The words that we use][the-words-that-we-use].
