Complete and total n00b!! Need walkthrough.

I've had my computer for about a year and I love it to death, but even though I have openSUSE installed, I have no knowledge of the system itself. I built the computer with the help of a very knowledgeable friend and he kindly introduced me to Linux. Like I said, I love it, but I know nothing about code. I can navigate and use a computer fairly well but I am not learned on anything else.

All that to say, I downloaded Kdenlive for some very simple editing and as I saw in the readme, also downloaded MLT. I have installed a program from these types of zipped packages before but I can't remember how. I follow instructions well but I am not ready to type some command in wrong and ruin my system since I'm a total idiot concerning code. I've been at it for several hours trying to figure it out but after a while it's become apparent that I just don't have the knowledge or vocabulary for these types of instructions (for example, I'm pretty certain but not 100% that I'm posting in the right forum).

Sorry to bother you all, but I just need a simple breakdown of which files I need to run and in what order and all that jazz.

Thanks.
