# Using VFVS

The usage of VFVS is the same as the usage of VirtualFlow in general, which is described [here](/documentation-vf1/using-virtualflow.md). 

In addition for VFVS the input-files folder has to be prepared set up as described [here](/documentation-vf1/vfvs/using-vfvs/preparing-the-workflow.md#input-files-folder). 

All specific options/features which one can activate/configure in VFVS are described in the control file `tools/templates/all.ctrl`, where the values for all of them can be specified. These options/features include the setting up of the docking scenarios to be used:

* Number of docking scenarios
* Docking programs to be used
* Number of replicas per docking scenario
