<http://localhost:3000/hello/world> gives:

"Unknown action

No action responded to world"


I'm following along with <http://wiki.rubyonrails.org/rails/pages/
Tutorial> and what stands out are statements like:

"Now take a look at app/controllers/hello_controller.rb."

Which doesn't exist for me, I had to create multiple directories.  I
would've thought that a directory like "controllers" would be pre-
existing?

Anyhow, I was getting:

"Hello#index

Find me in app/views/hello/index.rhtml"

from both <http://localhost:3000/hello> and
<http://localhost:3000/hello/
index>, but seem to have lost the thread of the tutorial.


I know that my .rhtml file should be using the variable which is defined
elsewhere, but it's not clear from this tutorial how to do that
(entirely).  It doesn't specify what each file should look like in its
entirety, and I, for instance, can't follow the instruction to "Notice
the index function," because there's no such function in the file which
I
created. Should I create such a function?  No doubt, but the discrepancy
indicates that perhaps my configuration is mucked up.  The index
function
should've been created by...?

In any event, here's my decidedly primitive script which I'm using to
run
my ruby stuff, and it's output:
