Include additional javsripts in the header

I am completely lost in OJS 3. I thought I found the header.tpl but no matter what I did to it, there is no change to the website pages. I shall appreciate it very much if someone can show me how to make changes to the header to include more javascripts AND in general where I should look if I want to customize the look of the website.

Thank you very much.
