-A lightweight C++11 Distributed Hash Table implementation
+A lightweight C++11 Distributed Hash Table implementation originally based on https://github.com/jech/dht by Juliusz Chroboczek.
 
- * Light C++11 Kademlia DHT library
- * Simple distributed map API
- * Support for storage of arbitrary values (not just IPs)
- * Optional public key cryptography layer providing data signature and encryption (using GnuTLS)
- * Fast bootstrap and announce time
- * Not compatible with Bittorrent DHT (mainline).
- * Originally based on https://github.com/jech/dht by Juliusz Chroboczek
+ * Light and fast C++11 Kademlia DHT library.
+ * Distributed shared key->value data-store
+ * Clean and powerfull distributed map API.
+ * Storage of arbitrary binary values up to 64 kB. Keys are 160 bits long.
+ * Optional public key cryptography layer providing data signature and encryption (using GnuTLS).
+ * IPv4 and IPv6 support.

+The `tools` directory includes two simple example programs :
+* `dhtnode`, a command line tool, mostly used for debuging, allowing to perform all operations supported by the library with string values.
+* `dhtchat`, a very simple example of a chat client working over the dht.

 Example program launching a DHT node, connecting to the network and performing some basic operations:
 ```c++
 #include <opendht.h>
