Update docs and change license.

* More relevant. They are pretty much the same as when the software was
  first released and several aspects are not longer valid. Also some things
  could be clearer.
* This was under MIT but I really prefer my stuff to be public domain. Switched
  license. There are a few patches from others but they are not [legally
  significant](https://www.gnu.org/prep/maintain/maintain.html#Legally-Significant)
  and will soon be mostly removed anyway since they mostly relate to the
  error page which I will be removing.
* Took the wiki content, made it less verbose and moved it into the readme
  file.

+= Purpose
+
+Rack Legacy tries to provide interaction with legacy environments like
+PHP and CGI while still getting the Rack portability so you don't need
+a full Apache stack.
+
+This software is currently BETA quality. Use at your own risk.
+
+= Purpose
+
+The PRIMARY use case for this software is for development of an
+application where Ruby is being used but there are also some legacy
+PHP or CGI that is running along-side the Ruby application. This
+middleware allows you to do that development without the full Apache
+stack.
+
+When you take the application to a production environment you can either
+leave this middleware in or use a full Apache stack to get added
+performance and security.
+
+= USAGE
+
+== Installation
+
+    gem install rack-legacy
+
+== Generic Rack Integration
+
+Put the following in your rack stack:
+
+    require 'rack-legacy'
+    use Rack::Legacy::Php, 'public'
+
+== Rails Usage
+
+In your Gemfile
+
+    gem 'rack-legacy'
+
+In your application.rb:
+
+    config.middleware.insert_before \
+      ActionDispatch::Static, Rack::Legacy::Php, Rails.public_path
+
+Rails < 3 is not well supported. This is because Rack::Static (later
+turned into ActionDispatch::Static) is not in the Rails stack but
+instead processed in the stack that loads Rails prior to Rails running.
+This means you cannot insert any middleware before it. This software
+previously had some hacks to work around this but with the release of
+Rails 3 the hacks where not necessary and therefore removed.
+
+If you still need to use rack-legacy on a Rails 2 app see version 0.1.5.
+
+== Pure PHP/CGI
+
+Got a project that is nothing but PHP or CGI? Run `rack_legacy` in the
+website root directory and it will start serving the files.
+
+= LICENSE
+
+This is free and unencumbered software released into the public domain.
+
+= CREDIT
+
+This gem was developed by Eric Anderson (http://pixelwareinc.com)
+partially via work done under Red Tusk Studios (http://redtusk.com) and
+Southern Web Group (http://www.southernwebgroup.com).

 Things I will probably not implement but I welcome others to do.
 
-== Security
+= Security
 
 I tried to not do anything dumb but this code isn't audited either.
 For that reason I recommend this tool be used for only for development
-purposes and not used in production until someone takes a closer look
-at security.
+purposes.
 
-== Performance
+= Performance
 
 We could possibly support FastCGI and some sort of mod_php-like
 interface to allow greater performance. Useful if someone uses this
 in production. 
 
-== Corner Cases
-
-I doubt I am supporting the full CGI spec. I am sure there are corner
-cases where this software doesn't work. Also I don't know what the
-implications are for things like php safe mode and other php corner
-cases.
-
-== Standard Error Capture Hacks
+= Standard Error Capture Hacks
 
 Currently I am using a tempfile to capture the standard error from
 the CGI script. This seems a little hackish. Would like to just
 capture the standard error directly.
-
-== Forward Thinking
-
-This code is un-tested in Ruby 1.9
