-i2pd is a full-featured C++ implementation of 
-[I2P](https://geti2p.net/en/about/intro) client.
+i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.
 
-I2P (Invisible Internet Project) is anonymous network which works on top of 
-public Internet. Privacy and anonymity are achieved by strong encryption and 
-bouncing your traffic through thousands of I2P nodes all around the world.
+I2P (Invisible Internet Protocol) is a universal anonymous network layer. 
+All communications over I2P are anonymous and end-to-end encrypted, participants
+don't reveal their real IP addresses. 
 
-We are building network which helps people to communicate and share information 
+I2P client is a software used for building and using anonymous I2P 
+networks. Such networks are commonly used for anonymous peer-to-peer 
+applications (filesharing, cryptocurrencies) and anonymous client-server 
+applications (websites, instant messengers, chat-servers).
+
+I2P allows people from all around the world to communicate and share information
 without restrictions.
