Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.


By default rails application was created with sqlite database, which is a light weight database.


Now its time to start the server and check the welcome page

Run the below command in the application directory structure.

> rails s

=> Booting WEBrick
=> Rails 3.2.2 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2012-07-19 12:16:05] INFO  WEBrick 1.3.1
[2012-07-19 12:16:05] INFO  ruby 1.9.2 (2011-07-09) [i686-linux]
[2012-07-19 12:16:05] INFO  WEBrick::HTTPServer#start: pid=27799 port=3000


Now you can browse the application with url: http://localhost:3000 to see the welocme page.
