 ## Usage
 
 1.config
-at config/environments/*.rb
+at ```config/environments/*.rb```
 
-    config.cache_store = :bitzer_store, {
-      :default => [:mem_cache_store, "server0"],
-      :top_page => [:mem_cache_store, "server1", "server2"],
-      :obj => [:dalli, "server3"],
-      :footer => [:file_store, "/tmp"]
-    }
+```ruby
+MyApp::Application.configure do
+  BitzerStore.configure(config) do |cache|
+    cache.default :mem_cache_store, "server0"
+    cache.top_page :mem_cache_store, "server1", "server2"
+    cache.obj :dalli, "server3" 
+    cache.footer :file_store, "/tmp"
+  end
+end
+```
 
-Each hash key is name of cache cluster.
-You should supply :default key which is used to default cache cluster.
+The ```xxx``` of ```cache.xxx``` is name of cache cluster.
+You should supply ```cache.default``` which is used to cache cluster of default.
 
+You can specify the setting common items. 
+Setting common items will be overwritten with individual setting.
+
+```ruby
+MyApp::Application.configure do
+  BitzerStore.configure(config) do |cache|
+    cache.common_setting :memcache_store, "server0", :expires_in => 600
+    cache.default :namespace => "tsu"
+    cache.top_page :dalli, "server1"
+  end
+end
+```
+
+The contents of the above is the same as below.
+
+```ruby
+MyApp::Application.configure do
+  BitzerStore.configure(config) do |cache|
+    cache.default :memcache_store, "server0", :expires_in => 600, :namespace => "tsu"
+    cache.top_page :dalli, "server1", :expires_in => 600 
+  end
+end
+```
+
 2.Rails.cache
 When specify no name, to use default cache cluster.
 
-    Rails.cache.read("a")
+```ruby
+Rails.cache.read("a")
+```
 
 Supply an options with a :sheep key. It's value is cache cluster name.
 
-    Rails.cache.read("a", :sheep => :cluster_a)
+```ruby
+Rails.cache.read("a", :sheep => :cluster_a)
+```
 
 caches_action, fragment_cache are the same.
+
+```ruby
+<% cache "page", :sheep => :cluster_a do %>
+  <%= somethong %>
+<% end %>
+```
