WPF: Bind Command with Checkbox

I am pretty new to WPF and MVVM so this may be a very easy question. I have an app with a button and a checkbox. Once the button is clicked it runs a command that then runs a script. The checkbox is an option to view an internet browser as the script runs. I am wondering how I can pass in wheather the checkbox is checked or not once the button is selected. I changed some of the coding names to be more basic. Here is my Xaml:

<StackPanel Margin="10">
        <CheckBox Content="Option" IsChecked="True"  />
        <Button Height="20"
                Content="Run Script"
                Command="{Binding Script }"
                />
    </StackPanel>

And here is the the ViewModel:

class MainWindowViewModel
{
    public ICommand script{ get; set; }

    public MainWindowViewModel()
    {
        script = new RelayCommand(o => MainButtonClick());
    }

    private void MainButtonClick()
    {
        Program start = new Program();
        start.Begin();
    }
}

You can bind the IsChecked of the CheckBox to a property in the ViewModel. Something like this should work:

<CheckBox Content="Option" IsChecked="{Binding ShowBrowser}"  />

public bool ShowBrowser {get; set;}

You can then use the ShowBrowser property in your MainButtonClick method

Or you could use a Command Parameter as dymanoid pointed out in the comments. Like so:

<CheckBox Name="ShowBrowser" Content="Option" IsChecked="True"  />
<Button Height="20"
    Content="Run Script"
    Command="{Binding Script }"
    CommandParameter="{Binding ElementName=ShowBrowser, Path=IsChecked} 
    />

And then your Method would look like this:

private void MainButtonClick(bool showBrowser)
{
    Program start = new Program();
    start.Begin();
}

This is of course assuming your RelayCommand class can handle parameters
