 User Manual
 ====================================

+Version: VECTO 2.2 / VectoCore 3.0.2 / VectoCmd 3.0.2
 
-VECTO 2.2 / VectoCore 3.0.2
+---
+
+VECTO is a tool for the calculation of energy consumption and CO~2~ emissions of vehicles. It models the components of a heavy-duty vehicle and simulates a virtual drive on a route. The goal is to provide a standardized way of calculating the energy consumption (fuel consumption) and corresponding CO~2~ emissions.
+
+
+This User Manual consists of 3 Parts:
+
+- [Graphical User Interface](#user-interface):
+    : Here graphical user interface of VECTO with all windows and configuration possibilities is described.
+- [Simulation Model](#simulation-model):
+    : This chapter describes the used component models and formulas which are implemented in the software. 
+- [Input and Output](#input-and-output):
+    : The input and output file formats are described in this chapter.
