+## QWK and QWK-Net Style Networks
+As like all other such as FidoNet-Style (FTN) networks, ENiGMA½ considers QWK external to the system but can import and export the format.
+
+### Supported Standards
+QWK must be considered a semi-standard as there are many implementations. What follows is a short & incomplete list of such standards ENiGMA½ supports:
+* The basic [QWK packet format](http://fileformats.archiveteam.org/wiki/QWK).
+* [QWKE extensions](https://github.com/wwivbbs/wwiv/blob/master/specs/qwk/qwke.txt).
+* [Synchronet BBS style extensions](http://wiki.synchro.net/ref:qwk) such as `HEADERS.DAT`, `@` kludges, and UTF-8 handling.
+
+
+### Configuration
+QWK configuration occurs in the `messageNetworks.qwk` config block of `config.hjson`. As QWK wants to deal with conference numbers and ENiGMA½ uses area tags (conferences and conference tags are only used for logical grouping), a mapping can be made.
+
+:information_source: During a regular, non QWK-Net exports, conference numbers can be auto-generated. Note that for QWK-Net style networks, you will need to create mappings however.
+
+:TODO: information on QWK-Net type setup here
+
+Example:
+```hjson
+{
+    messageNetworks: {
+        qwk: {
+            areas: {
+                general: {          // local ENiGMA½ area tag
+                    conference: 1   // conference number to map to
+                }
+            }
+        }
+    }
+}
+```
+
+### oputil
+The `oputil.js` utility can export packet files, dump the messages of a packet to stdout, etc.
+
+TODO: Examples, etc.
+TODO: Link to oputil, update --help there.
+
+### Offline Readers
+A few of the offline readers that have been tested with QWK packet files produced by ENiGMA:
+
+| Software | Status | Notes |
+|----------|--------|-------|
+| MultiMail/Win v0.52 | Supported | Private mail seems to break even with bundles from other systems |
+| SkyReader/W32 v1.00 | Supported | Works well. No QWKE or HEADERS.DAT support. Gets confused with low conference numbers. |
+
+There are also [many other readers](https://www.softwolves.pp.se/old/2000/faq/bwprod) for various systems.
