My teacher was going to give us a rubric for what needs to be in the paper, she didn't. So my question is what should I put in the outline for...

Since I am not sure what kind of class this is for, I am going to share some different kinds of ideas.  A paper like this might be for a French class, a history class, a geography class, or a world cultures class.  Which class you are preparing your paper for would require a different kind of focus. 

An outline is easy.  Microsoft Word practically does your work for you!  Once you start typing in Roman numerals, the software will guide you.  So all we need to do is talk about the "shape" of the outline.  You will need to begin with a Roman Numeral for your first paragraph, which should be an introduction.  The points you need to list are your main idea, what you want the reader to "get" when he or she is done, some general information about France, just to get the reader "situated," and a kind of preview statement that will tell the reader the points you plan on making. So, if this paper is for a history class, for example, the points you make might be about medieval France, the French Revolution, and modern France.  There are plenty of other topics to cover, so remember, these are just examples. 

Your next Roman numeral should be the first point you cover.  Then below that belong the details that support that topic. Each Roman numeral that follows should cover one topic, with supporting details. 

Finally, your last Roman numeral should be the conclusion.  What you want to list in that section is a restatement of your main idea and a reminder of the points you have made in the previous Roman numerals. 

Some teachers require students to write complete sentences in outlines, but others do not. This is something you will have to check with your teacher about.

Now, we have talked already about the kinds of topics that would make sense for a history class.  If this paper is for a French class, some possible topics might be French literature and countries where French is spoken.  A geography paper might focus on the physical geography of France, things like mountains, rivers, etc. and on topics like natural resources and population.  A world cultures class paper could include art, music, architecture, food, and so on. 

I hope this is of some use to you.  Good luck!
