Learn how to install Crystal locally to solve Exercism's exercises on your own machine
Crystal is available on Linux, macOS, and Windows.
What to note is that Crystal's windows support is experimental. Thereby, it is not recommended to use it in production since issues may occur. Instead for windows development, it is recommended to use WSL (Windows Subsystem for Linux). It is a free feature of windows 10(1903+) and 11 which allows developer to run a linux environment without the need of a virtual machine.
Use one of the installation guides for instructions on installing Crystal.
