# Using VirtualFlow

VirtualFlow is managed, used, and controlled by:

1. A number of commands in the `tools/` folder
2. The control (configuration) files
   1. The file `tools/templates/all.ctrl` (before initializing the workflow)
   2. The files in the folder `workflow/control/` (after initializing the workflow)

The configuration files and the commands are described in the next subsections for VirtualFlow in general. Additional information on specific modules of VirtualFlow (VFLP or VFVS) might be present in the corresponding chapters.
