         # this will download composer binary file and generate a composer.phar on the current directory
      
         $ mv composer.phar /usr/local/bin/composer
         # move composer.phar from current directory under bin directory so it will be available globally and change its name from composer.phar to composer so it will easy to use as command.
      
         $ chmod +x /usr/local/bin/composer
         # set executable permission to current user for the composer file
