 Flexible sharding access for Ruby on Rails with ActiveRecord
 
 ## Sharding model generator
 
+```
     rails g sengiri:model mygroup user name:string
+```
 
 ## database.yml
 
+```ruby
     mysql: &mysql
       adapter: mysql2
       encoding: utf8
       reconnect: false
       pool: 1
       username: root
       password:
       host: localhost
     
-    mygroup_shards_first: # define shard as 'first'
+    mygroup_shard_first: # define shard as 'first'
       <<: *mysql
       database: mygroup_1
       host: hosta
-    mygroup_shards_second: # define shard as 'second'
+    mygroup_shard_second: # define shard as 'second'
       <<: *mysql
       database: mygroup_2
       host: hostb
-    mygroup_shards_third: # define shard as 'third'
+    mygroup_shard_third: # define shard as 'third'
       <<: *mysql
       database: mygroup_3
       host: hostc
     .
     .
     .
+```
 
 ## Sharding migration
 
+ActiveRecord task is available on every shard.
+
+```ruby
     rake sengiri:mygroup:db:create
     rake sengiri:mygroup:db:migrate
-
+    rake sengiri:mygroup:db:rollback
+    ...
+```
     
 ## Sharding access
 
+On a shard, ActiveRecord class is given.
+
+```ruby
     User.shard('second') do |shard|
-      shard.all.limit(10) # query on db 'mygroup_1'
+      shard.all.limit(10)   # query on db 'mygroup_2'
+      shard.find(1)         # query on db 'mygroup_2'
     end
+```
 
+Every shard.
 
+```ruby
     User.shards do |shard|
-      shard.all.limit(10) # query on all db 'mygroup_1', 'mygroup_2', 'mygroup_3'
+      shard.all.limit(10) # query on all shards 'mygroup_1', 'mygroup_2', 'mygroup_3'
     end
+```
 
+All records from all shards.
+
+```ruby
+    all_records = User.all.broadcast
+```
+
 ## Transaction
 
+In a shard transaction.
+
+```ruby
     User.shard('second').transaction do
       # in mygroup_2 transaction
     end
+```
 
+In all shards transaction.
 
+```ruby
     User.transaction do
       # in mygroup_1, mygroup_2 and mygroup_3 transaction
     end
+```
 
+This is same as below
 
-    # This is same as below
-
-
+```ruby
     User.shard('first').transaction do
       User.shard('second').transaction do
         User.shard('third').transaction do
         end
       end
     end
