-A Ruby implementation of a Kademlia-style Distributed Hash Table.
+A Ruby implementation of a Distributed Hash Table.
+
+Basic usage
+===========
+
+You can create instance of `DHT::Hash` and use like normal `Hash`
+
+```ruby
+require 'dht/hash'
+
+hash = DHT::Hash.new
+hash[:key] = :value # => :value
+hash[:key] # => :value
+```
+
+Advanced usage
+==============
+
+You can create instance of `DHT::Hash` with few options
+
+* **host** - your IP address or domain
+* **port** - your open port where DHT::Hash will be listen
+* **name** - name of your node
+* **node** - bootstrap node
+
+```ruby
+require 'dht/hash'
+
+hash = DHT::Hash.new :host => "mydomain.com" # default 127.0.0.1
+                     :port => 8080 # default 3000
+                     :name => "my_name" # default "node"
+                     :node => { :id => "bootstrap", :addr => 'tcp://domain.com:2042' } # boostrap node
+                     :explorer => true # enable explorer
+```
