 Setup werc with Plan 9's httpd
 ==============================
 
-Coming soon, thanks to soul9!
+
+There are two main options, you can use Russ Cox's magic to cgi translator
+(found in his contrib dir as cgi.c), or you can use the following script which
+while simpler, it also lacks some features at the moment.
+
+Thanks to soul9 for the original idea of wrapping werc in a shell script that
+would setup a cgi-like environment!
+
+
+    #!/bin/rc
+
+    SERVER_NAME=$2
+    REQUEST_URI=`{echo $*(15)}
+    REQUEST_URI=$REQUEST_URI(2)
+    REQUEST_URI=/
+    REQUEST_METHOD=$*(16)
+    PLAN9=/
+
+
+    echo 'HTTP/1.0 200 Ok
+    Connection: close
+    Server: werc/9.9.9' # This is whatever you like
+
+
+    cd /usr/web/bin/
+    rfork
+    /bin/rc < ./werc.rc >[2]/usr/glenda/tmp/w/log # Use whatever location you like to log stderr, but make sure it is writable by none.
+
+Call this script werc-wrap, and put it in /rc/bin/ip/httpd/
+
+Then in your /sys/lib/httpd.rewrite  add a line like:
+
+    /w @/magic/werc-wrap
+
+And this will run werc for all stuff under /w. Note that apparently httpd is
+incapable of internally remapping the root directory, so until a solution is
+found for this, you will have to keep your site in a sub-directory of the web
+server root.
+
+**Notes**: This is experimental and work in progress, there are a couple of issues
+with the werc code itself that might need fixing, in particular you will need
+to replace the '%($"extraHeaders%)' in lib/headers.tpl with '% echo
+$"extraHeaders' no clue why.
