How to set up Crystal, step by step
Open Terminal. On a Mac it's in Applications ▸ Utilities, or press Cmd+Space and type Terminal. On Linux, press Ctrl+Alt+T. Paste the command and press Enter.
Run Crystal --help to see the available commands, and
Crystal --version to confirm the install worked. If your shell complains about
permissions, that project usually documents a corrected command on its own site.

On mobile
Crystal is a command-line tool, so there is no phone app for it — a phone has no shell to run it in. You'll need a desktop, or a remote shell into a machine that has one.
Crystal is developed by its own authors. This page is an independent reference; we are not affiliated with or sponsored by the project. The command shown here was reproduced from the project's public documentation — always check the project's own documentation before running anything.
