-* ImageMagick
-
-*I haven't tried lower version yet.*
-
-## Getting started
-
-**1. Add DalliCaptcha to your gemfile**
-
-```ruby
-  gem 'dalli_captcha'
-or
-  gem 'dalli_captcha',:git =>"git://github.com/javyliu/dalli_captcha.git"
-```
-
-**2. Generate initializer**
-
-    rails g dalli_captcha:install
-
-It'll generate `config/initializers/dalli_captcha.rb`, and you can configure all options here.
-
-**3. Mount DalliCaptcha::Engine in your router.rb**
-
-```ruby
-mount DalliCaptcha::Engine => '/captcha', :as => :captcha
-```
-
-
-**4. Add before_filter to your controller**
-
-```ruby
-class PostsController < ApplicationController
-    before_filter :generate_captcha_key, :only => [:new, :edit]
-    ......
-end
-```
-
-**4. Add module to your model**
-
-```ruby
-class Post < ActiveRecord::Base
-    include DalliCaptcha::Model
-end
-```
-
-if you set `config.active_record.whitelist_attributes = true` in `config/application.rb`, remember to add attr_accessible to your model:
-
-```ruby
-attr_accessible :captcha, :captcha_key
-```
-
-to your model.
-
-**5. Use DalliCaptcha in your view**
-
-```erb
-<%= image_tag(captcha_path(:timestamp => Time.now.to_i), :alt => "captcha") %>
-<%= f.text_field :captcha %>
-<%= f.hidden_field :captcha_key, :value => session[:captcha_key] %>
-```
-
-**6. Use DalliCaptcha in your controller**
-
-```ruby
-    # Initialize a post
-    @post = Post.new(:title => "test")
-
-    # valid with captcha
-    @post.valid?
-
-    # save with captcha
-    @post.save
-
-    # valid without captcha
-    @post.valid_without_captcha?
-
-    # save without captcha
-    @post.save_without_captcha
-```
-
-
-Enjoy it!
