You can put the program anywhere, I put it on the desktop.
Under the program folder you have a folder called Modules, this is where you put the sim file (which is the panel).
You then run the SimVimPanel app. (which is the main program) by double clicking it.
You might need to set the "rights" on the app by, for example, typing the following in a terminal (being in the correct folder)
chmod 755 SimVimPanel
