2. WHY?
   • Other frameworks seems too bloated for your
   project.
   
   • Need more visibility/transparency on how the app
   is put together.
   
   • Don’t like the default libraries provided by the
   other frameworks & no easy way to

   circumvent them.

3. COMPOSER
   • Pick and choose libraries you want to put together
   on Packagist (https://packagist.org/).
   
   • Compose your own composer.json.
   
   • Choose a package namespace for your own
   project.
   
   • Reference: https://getcomposer.org/

10. THE IMPLEMENTATION
    • TDD: Red, Green, Refactor.
    
    • Use your own namespace to take advantage of
    Composer’s autoload mechanism.
    
    • Don’t get ahead of yourself.
