Trying to get the “Welcome Aboard” page

Hello, I'm new to Rails and wanted to ask a super and basic question. I can't seem to get the "Welcome Aboard" page.

The only page I can get his this one:

The current tutorial I am using is this:

http://guides.rubyonrails.org/getting_started.html

I've tried both versions of
rails new appname

and

rails new blog --skip-spring --skip-listen

For environment reference:
Microsoft Windows [Version 6.1.7601]

ruby 2.2.6p396 (2016-11-15 revision 56800) [i386-mingw32]

C:\Users\FR62496>rails -v
Rails 5.0.2

Here's what I've been doing

$ rails new blog

$ cd blog

$ bundle install

$ bundle update

$ bin/rails generate controller Welcome index

I do see that the controller Welcome folders and items show up:

But I still don't see the supposed Welcome Aboard page. It's still stuck on yay! You're on rails! page.

Here's what happens when I do $ rails server:

$ rails server

=> Run `rails server -h` for more startup options
