+# Béziers for Beginners
+
+Bézier curves are parametric curves defined by a set of control points. These points’ positions in relation to one another define the shape of the curve. In OpenSCAD these points are contained in a list. The simplest cubic Bézier curve has 4 control points. The first and last control points are the endpoints of the curve, but the other two control points do not lie on the curve itself.
+
+To work with Béziers in OpenSCAD we need to load the Bézier extension BOSL2/beziers.scad in addition to BOSL2/std.scad.
+ 
+To visualize a Bézier curve we can use the module debug_bezier().
+
+```openscad2d
+include<BOSL2/std.scad>
+include<BOSL2/beziers.scad>
+
+bez = [[20,0], [40,10], [0,40], [20,60]];
+debug_bezier(bez);
+```
