+
+To build a kernel for use with the loadable kernel module, follow these
+steps:
+	1. do "make bsd"
+
+	2. cd to the "BSD" directory and type "make install"
+
+	3. run "4bsd/minstall" as root
+
+	4. build a new kernel
+
+	5. install and reboot with the new kernel
+
+	6. use modload(8) to load the packet filter with:
+		modload if_ipl.o
+
+	7. do "modstat" to confirm that it has been loaded successfully.
+
+There is no need to use mknod to create the device in /dev;
+- upon loading the module, it will create itself with the correct values,
+  under the name (IPL_NAME) from the Makefile.  It will also remove itself
+  from /dev when it is modunload'd.

+To build a kernel with the IP filter, follow these steps:
+
+	1. do "make bsd"
+
+	2. cd to the "BSD" directory and type "make install"
+
+	3. run "4bsd/kinstall" as root
+
+	4. build a new kernel
+
+	5. create devices for IP Filter as follows (assuming it was
+	   installed into the device table as char dev 20):
+		mknod /dev/ipl c 20 0
+		mknod /dev/ipnat c 20 1
+		mknod /dev/ipstate c 20 2
+		mknod /dev/ipauth c 20 3
+
+	6. install and reboot with the new kernel
