+## Was ist Web4Rail?
+
+Web4Rail is a model railway control software.
+It is designed to be used from any device featuring a web browser.
+
+![Screenshot](doc/images/Web4Rail.screenshot01.png)
+
+It is a client-server application. In other words
+
+* The program itself is running on a central computer, connected to your digital model 
+  railway layout.
+* In order to let a user interact with the railway, an arbitrary web-enabled device (PC, Laptop, Tablet, Smartphone, TV, ...) can 
+  connect to the central computer and take control.
+* Thus, it is even possible to let several users and devices control the layout simultaneously!
+
+## Digital control of the layout
+
+The control signal for the layout is generated using [SRCPD] – this program *may* also 
+be running on the same hardware as the Web4Rail program.
