Set up a default route and remove or rename this file
Routes are set up in config/routes.rb.

.quick dumb question…do i setup the default route in the command
prompt terminal or an IDE? im learning as i go here…i tried running
config/routes.rb in a terminal and got the following error

virtualrails@jay ~/blog $ config/routes.rb
bash: config/routes.rb: Permission denied
