+To install Mozart and its dependencies, without conflicting with the dependencies of your project, it is recommended that you install Mozart as a global package, if you choose to install Mozart via Composer.

+Using the `global` command when installing Mozart, it will be installed as a system wide package:

+composer global require coenjacobs/mozart

 ```
 composer require coenjacobs/mozart --dev
 ```
 
 This gives you a bin file named `mozart` inside your `vendor/bin` directory, after loading the whole package inside your project. Try running `vendor/bin/mozart` to verify it works.
