I want to add dots in my table of contents, and modify its size. I know there were tons of questions in the style, but I'm incredibly dumb. I don't even know what the \begin command do. I also want to change the language. I don't want it to write "contents" but "table des matieres" which is in french.
Here are my 2 lines
\newpage
\tableofcontents
\addtocontents{toc}{~\hfill\textbf{Page}\par}
Please tell me what I should add and where. I tried many stuff, and I don't have time in front of me to learn latex.
Thank you very much

titletocpackage, which comes withtitlesec, but can be used independently, has a\dottedcontentscommand, and other tools to format the title of contents. See §6, pp. 14–20 of the titlesec documentation. – Bernard Mar 20 '20 at 12:02
