+# lib9p
+
+lib9p is a server library implementing 9p2000, 9p2000.u and 9p2000.L revisions
+of 9P protocol. It is being developed primarily as a backend for virtio-9p in
+BHyVe, the FreeBSD hypervisor.
+
+# Features
+
+* 9p2000, 9p2000.u and 9p2000.L protocol support
+* Built-in TCP transport
+
+# Supported operating systems
+
+* FreeBSD (>=10)
+* macOS (>=10.9)
