+coturn is a free open source implementation of TURN and STUN Server.
+The TURN Server is a VoIP media traffic NAT traversal server and gateway.
 
-# Free open source implementation of TURN and STUN Server #
+## Installing / Getting started
 
-The TURN Server is a VoIP media traffic NAT traversal server and gateway. It can be used as a general-purpose network traffic TURN server and gateway, too.
+Linux distros may have a version of coturn which you can install by
+```
+apt install coturn
+turnserver --log-file stdout
+```
 
-On-line management interface (over telnet or over HTTPS) for the TURN server is available.
+Or run coturn using docker container:
+```
+docker run -d -p 3478:3478 -p 3478:3478/udp -p 5349:5349 -p 5349:5349/udp -p 49152-65535:49152-65535/udp coturn/coturn
+```
+See more details about using docker container [Docker Readme](https://github.com/coturn/coturn/blob/master/docker/coturn/README.md)
 
-The implementation also includes some extra experimental features.

+Performance and Load Balancing:
+
 When used as a part of an ICE solution, for VoIP connectivity, this TURN server can handle thousands simultaneous calls per CPU (when TURN protocol is used) or tens of thousands calls when only STUN protocol is used. For virtually unlimited scalability a load balancing scheme can be used. The load balancing can be implemented with the following tools (either one or a combination of them):
