The slider's general settings can be found in the sidebar of the slider's admin interface. The description of each setting can be seen if you hover the setting's label.
Inside the 'Presets' panel, you can save setting configuration in order to easily reuse them for other sliders. After you decided on a certain configuration you just need to click on the 'Save New' button and then you will be prompted to specify a name for the saved preset. The preset will then be saved and added to the list of saved presets. You can later update the configuration of a certain preset or delete it if you want.
The last panel in the sidebar is for breakpoints. Breakpoints allow you to modify the look of the slider for different window sizes. Each breakpoint allows you to set the width of the window for which the breakpoint will apply, and then add several settings which will override the general settings.
