+Summary:        VNC server accessible from a web browser

+%description
+KasmVNC provides remote web-based access to a Desktop or application. 
+While VNC is in the name, KasmVNC differs from other VNC variants such 
+as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB 
+specification which defines VNC, in order to support modern technologies 
+and increase security. KasmVNC is accessed by users from any modern 
+browser and does not support legacy VNC viewer applications. KasmVNC 
+uses a modern YAML based configuration at the server and user level, 
+allowing for ease of management. KasmVNC is maintained by Kasm 
+Technologies Corp, www.kasmweb.com.
+
+WARNING: this package requires EPEL.
