-As much as possible, \e{XTrackCAD} is designed to operate the same as pencil and paper: create tracks by simply dragging the mouse, place turnouts anywhere on existing tracks, use circles for initial design and create stall tracks by drawing from the turntable. 
+ \e{XTrackCAD} was designed to operate in a similar way to pencil and paper: You can draw tracks by dragging the mouse, you select and place turnout "templates" anywhere on existing tracks, and you can use fixed radii for initial design. 
+ 
+But extra capabilities have been added that give more power by using FlexTracks (Cornu) you have tracks that automatically redraw as you drag turnouts around, creating smooth curves, you can zoom in and out, and of course, undo and deleting tracks are easier!
+
+You don't have to be an expert CAD user to make the most of \e{XTrackCAD} but the program will ensure that dimensions, radii and angles are accurate. 
+
+You don't have to specify line lengths or angles and just draw. But if you want to be more precise, you can enter precise dimensions both in real-world and scale sizes.
+
+\e{XTrackCAD} is a specialized CAD for railway modelling, it deals with tracks as tracks, not as line segments. Tracks are connected correctly to each other and with endpoints of turnouts and other components. 
+
+As you zoom in, the two rails are drawn and then ties are added.
