How & where do you edit video and set to music? - video set viêt

Should I fill a music video. I have no idea how and where to start to download videos, edit, and time them to the music .... where I can do and simple instructions on how to be great. I can do anything material, but I think a bit more general knowledge of computers. Thanks for any help
