I'm having the darnedest time understanding something I'm sure is very simple (at least was under other web dev platforms where I would do a href...C:\windows\apps\home.html). I'm trying to set up a link to my home page

I have an application controller:
Code:
# Filters added to this controller apply to all controllers in the application.
# Likewise, all the methods added will be available for all controllers.

class ApplicationController < ActionController::Base
  layout "main" 
  helper :all # include all helpers, all the time
  protect_from_forgery # See ActionController::RequestForgeryProtection for details

  # Scrub sensitive parameters from your log
  # filter_parameter_logging :password
end
And a home controller:
Code:
class HomeController < ApplicationController
  def index
  end

end
and a main.html.erb:
Code:
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="content-type" content="text/html;charset=UTF-8" />
  <title>Pics4Flicks</title>
  <%= stylesheet_link_tag 'style' %>
</head>
  <body>
    <div id="container">
  <div id="top">
  </div>
  <div id="navbar">
  <ul>
    <li>Home</li>
    <li><%= link_to 'Movies', movies_path %></li> #this link works fine
    <li>DVD</li>
    <li>News</li>
    <li>Forum</li>
    <li>Contact</li>
  </ul>
</div>
I would like home to display the contents of my main.html.erb file. (or should it be application.html.erb?). To further confuse me, my home folder, under /apps/views/home has an index.html.erb file.

I must be mixing up my views (have I somehow created too many?) and perhaps not defining things properly in routes.rb. Hopefully haven't confused you all as much as I have myself. Any help most appreciated.
