 Rubikon
 =======
 
 Rubikon is a simple to use, yet powerful Ruby framework for building
 console-based applications.
+Rubikon aims to provide an easy to write and easy to read domain-specific
+language (DSL) to speed up development of command-line applications. With
+Rubikon it's a breeze to implement applications with only few options as well
+as more complex programs like RubyGems, Homebrew or even Git.
 
 ## Installation
 
-You can install Rubikon using RubyGem. This is the easiest way of installing

 If you run this application it will just print `Hello World!`.

+You can also add command-line options to your appication using `command`:

-      action 'hello' do
+      command :hello do
         puts 'Hello World!'
       end
 
     end
 
 This way your application would do nothing when called without options, but it
-would print `Hello World!` when called using `ruby myapp.rb --hello`.

+is code that is executed when the application is called with the command's name
+as the first argument - just like RubyGem's `install` or Git's `commit`.
 
-    set :dashed_options, false
+Another part of Rubikon's DSL are flags and options. Both are parameter types
+that change the behaviour of the application. While a flag is a parameter
+without arguments, an option may take one or more additional arguments. Typical
+examples for flags are `--debug` or `--verbose` (or short `-d` and `-v`).
+RubyGem's `--version` is an example for an option that requires additional
+arguments.
+Flags and options are easily added to your application's commands using
+Rubikon's DSL:
 
-Please see the `samples` directory for more in detail sample applications.
+    flag :more
+    option :name, 2
+    command :hello do
+      ...
+    end
 
 
+Please see the `samples` directory for more in detail sample applications.

 **Warning**:
 
 Rubikon is still in an early development stage. If you want to use it be aware
 that you will probably run into problems and or restrictions. See the
 Contribute section if you want to help making Rubikon better.

 ## About the name
 
 Rubikon is the German name of the river Rubicone in Italy. It had a historical
 relevance in ancient Rome when Julius Caesar crossed that river with his army
 and thereby declared war to the Roman senate. The phrase "to cross the Rubicon"
 originates from this event.
 
-You may also see Rubikon as a morphed composition of *"Ruby"* and *"console"*.
+You may also see Rubikon as a portmanteau word consisting of *"Ruby"* and
+*"console"*.
