If that video doesn't apply to your product though, I suggest simply googling 'vertical blinds fitting instructions' as there are loads of links that look like they might be useful there.
(I usually hate it when someone simply puts 'Why don't you Google it?' as an answer but in this case, since we know nothing about the product you've been given [or any fittings that might have come with it], that might well be the best thing to do).
Very easy to install and usually just 2 or 3 screws. The one thing I would say though is to make sure to leave enough space between blind and window frame for blind to move properly and not catch on window fittings like handles.
