Composer is the most flexible
way to get started with Silex. Create a directory to host your Silex
application and run the following command to create a
composer require silex/silex "~2.0"
Then, create a bootstrap file as explained in the documentation.
The easiest way to get started with Silex is to get started with the Silex Skeleton:
composer create-project fabpot/silex-skeleton path/to/install "~2.0"
