 ## Usage
 
+### Direct access to UMI

 So far, you can only get direct access the the Java API functions. To get it:
 
 ```ruby
 require 'universa'

+### Use UMI service (alfa state)
+
+The Universa::Service greatly simplify work taking all boilerplate. Just create objects almost as usual and use them
+as is they are local:
+
+```ruby
+key = PrivateKey,new(open('mykey.private.unikey', 'rb').read)
+contract = Contract.new(key)
+
+contract.seal()
+p contract.check()
+```
+
+The system will create UMI server and do all the work for you. Look at the RemoteAdapter class to see how does it
+work. Soon we'll add adapters for all frequently used Universa classes.
