# How to use .sty in writting in latex?

I need to write my thesis in latex for which we got .sty file (I didn't write it myself). I have no clue what I need to do to or need to write in .tex file to ''activate'' those styles.

If I understood correctly there are customized macros in .sty file but I don't know how are they working... Do I need to write some commands in .tex that are defined in .sty file? Or it should work if I write in .tex \usepackage{UNI-LJ-FE-Diploma} --> UNI-LJ-FE-Diploma is name of the .sty.

I use Texmaker on Linux so if you could tell me steps for this program I would be very grateful.

And if any of you know some good manual for better understanding of using .sty and how does it work... would be helpful too.

• Welcome to TeX.SE. If the file name of the style file is indeed UNI-LJ-FE-Diploma.sty, then typing \usepackage{UNI-LJ-FE-Diploma} after the \documentclass instruction and before \begin{document} is definitely the way to go. – Mico Feb 20 '16 at 13:34

A .sty file is just a regular package. Make sure it is in the same folder as your thesis and include it via \usepackage{UNI-LJ-FE-Diploma} in the preamble. There is in principle not more to say; if you want to better understand the style file ask the person from whom you got it. Since it seems, that you are not very experienced with latex I would say dont worry to much about it at the start. Just experiment a little with LaTeX and get used with it. Then, after you gained some experience you can always go back and deeper.
