 Installation instructions for eftp4linux
 
+Quick Install:
+
+eftp4linux needs a 2.2.x kernel which supports some special features
+and recent isdn4k-utils.
+
+Provided that your distribution is deliverd with such a 2.2.x kernel
+pre-installed, you might be able to use the basic functionality of
+the eftp4linux package without any other modifications to your system.
+You can test this by runing the shell script by changing to the
+"scripts"-sub-directory and typing
+
+sh check_system
+
+On success, you can directly go to the "This eftp4linux package"
+section and proceed. Otherwise, you need to upgrade your system.
+
+(Presence of the x25_utils packages, the isdnloop driver and the
+loopctrl binary is not checked by the script. But most features
+of eftp4linux will work without them. You can upgrade later after
+your first success events with eftp4linux).
