You can use this to install CLI utilities globally, all you need is to add the COMPOSER_HOME/vendor/bin dir to your PATH env var. COMPOSER_HOME is c:\Users\<user>\AppData\Roaming\Composer on Windows and /home/<user>/.composer on unix systems. If your system uses freedesktop.org standards, then it will first check XDG_CONFIG_HOME or default to /home/<user>/.config/composer Note: This path may vary depending on customizations to bin-dir in composer.json or the environmental variable COMPOSER_BIN_DIR.
