+WinDivert 2.2: Windows Packet Divert
+====================================
+
+1. Introduction
+---------------
+
+Windows Packet Divert (WinDivert) is a user-mode packet interception library
+for Windows 7, Windows 8 and Windows 10.
+
+WinDivert enables user-mode capturing/modifying/dropping of network packets
+sent to/from the Windows network stack.  In summary, WinDivert can:
+    - capture network packets
+    - filter/drop network packets
+    - sniff network packets
+    - (re)inject network packets
+    - modify network packets
+WinDivert can be used to implement user-mode packet filters, sniffers,
+firewalls, NATs, VPNs, IDSs, tunneling applications, etc..
+
+WinDivert supports the following features:
+    - packet interception, sniffing, or dropping modes
+    - support for loopback (localhost) traffic
+    - full IPv6 support
+    - network layer
+    - simple yet powerful API
+    - high-level filtering language
+    - filter priorities
+    - freely available under the terms of the GNU Lesser General Public
+      License (LGPLv3)

+
+2. Architecture
+---------------
+
+The basic architecture of WinDivert is as follows:
+
+                              +-----------------+
+                              |                 |
+                     +------->|    PROGRAM      |--------+
+                     |        | (WinDivert.dll) |        |
+                     |        +-----------------+        |
+                     |                                   | (3) re-injected
+                     | (2a) matching packet              |     packet
+                     |                                   |
+                     |                                   |
+ [user mode]         |                                   |
+ ....................|...................................|...................
+ [kernel mode]       |                                   |
+                     |                                   |
+                     |                                   |
+              +---------------+                          +----------------->
+  (1) packet  |               | (2b) non-matching packet
+ ------------>| WinDivert.sys |-------------------------------------------->
+              |               |
+              +---------------+
+
+The WinDivert.sys driver is installed below the Windows network stack.  The
+following actions occur:
+
+(1) A new packet enters the network stack and is intercepted by WinDivert.sys
+(2a) If the packet matches the PROGRAM-defined filter, it is diverted.  The
+    PROGRAM can then read the packet using a call to WinDivertRecv().
+(2b) If the packet does not match the filter, the packet continues as normal.
+(3) PROGRAM either drops, modifies, or re-injects the packet.  PROGRAM can
+    re-inject the (modified) using a call to WinDivertSend().
