 Example
 =======
 
+If the `meta.json` folder looks like:
+
+.. code-block:: 
+
+    {
+	"type":"file",
+	"title":"Syllabus",
+	"filename":"F24_Math100_syllabus.pdf",
+	"modules":["Course Information", "Week 1"],
+	"destination": "course_info/syllabus_schedule"
+    }
+
+then the file `F24_Math100_syllabus.pdf` will be put into two modules: `Course Information` and `Week 1`. 
+Within these two modules, its title will appear to students as `Syllabus`. The file will be located in `course_info/syllabus_schedule`, 
+which will be created if it did not already exist.
+
+Note that while a file cannot be simultaneously placed in multiple file structure locations using `meta.json`, if `meta.json` is updated, 
+the file will not automatically be deleted from any previous location unless that instance is specifically deleted.
