+## What is libhttpserver
+libhttpserver is a Free High-Performance library aimed at rapid development of embedded C++ servers:
+
+- It is designed and tuned to handle extremely high loads (tested with > 10k connections).
+- It uses modern C++ as the primary development language in order to achieve the first goal.
+- It is designed with REST as a primary design principle
+
+It is available under open source LGPLv2 license.
