Ichiloto is distributed with a Composer-installed CLI, which keeps the onboarding path simple for PHP developers.
composer global require ichiloto/console
After installation, verify that the command is available:
ichiloto --help

If the command is missing, check that Composer's global bin directory is on your PATH. On Unix-like systems that usually means adding the Composer global bin path to your shell profile.
The CLI is the front door for the engine, so it is worth fixing this properly instead of working around it. Most of the guide assumes the command is globally available.
