# First run

## Start
After extracting the zip file the file structure should be similar to the example image, depending on the version (GUI or batch).
![extracted](img/extracted.png)

To start CityDoctor the start.bat or start.sh should be used. It is possible to use the command in your own start scripts as needed.

The .bat/.sh file only contains the following command (example for windows and the GUI version):
```
java -classpath app/*;plugins/* de.hft.stuttgart.citydoctor2.gui.CityDoctorGUIStarter
```

!!! note
	The exact command has changed over the development history of CityDoctor.
	
For the batch version the command is similar and can be adapted for other operating systems.

!!! note
	The command can also be used for Linux and Mac but the ";" has to be replaced by ":".
