+Sverchok is a parametric tool for architects and designers. You can use it to
+program objects' shapes without knowing any programming languages.
+
+It is an add-on for Blender.
+
+Sverchok IS a parametric tool that relies on easy-to-use visual node-based
+design to create low-level data structures.
+
+Sverchok IS NOT an all-in-one tool. It does not have lighting and the rest
+of Blender's toolbox.
+
+It implements the approach of MATH + MESH + SPLINES + NURBS. It lets you operate
+with digits and math with high level language to manipulate nodes visually.
+
+Sverchok has been inspired by Grasshopper from Rhino 3D and uses a similar
+node-based visual programming principle. We are trying to bring this feature set
+to Blender users.
