+
+JuPedSim comes with four loosely coupled modules: 
+
+1. JPScore: The simulation core
+2. [JPSvis](https://cst.version.fz-juelich.de/jupedsim/jpsvis): Geometry and trajectories visualization tool
+3. [JPSreport](https://cst.version.fz-juelich.de/jupedsim/jpsreport): Implementation of different measurement methods to evaluate out of trajectories the density, the velocity and the flow.
+3. [JPSreditor](https://cst.version.fz-juelich.de/jupedsim/jpseditor): Geometry editor.
+
+
+
+
+
+## Usage
+`jpscore` is called  with initialization files (inifiles):
+
+```bash
+ jpscore config.xml
+```
+
+with `config.xml` a structured `xml` project file containing parameter definitions, agents distributions and other 
+important configurations to run a simulation.
