+Explicit Congestion Notification ([ECN])
+=========================================
 
+## No buffer by default
+
+After version v1.0.0.0, moesocks will default to no buffer at the application
+level. Smart buffer is expected from the kernel.
+
+In app buffer can still be tuned on by setting "tcpBufferSize" in
+`config.json` a value greater then 1.
