 To upload a document, I go down here to list of documents, and then I can go and add a document to my class. Then I just click on what I want to add. So here I can add some file from here. And then down here I have categories. So if I already had created categories before, then I can select them here. So here I had course outline as my only one. So if I want to create a new one, I just click on order. And then I can add the title of that new category. So test category, whatever. I could write here. And then I go on. I can select to concede when it will be available. And then I want the students to see it. Then on the next step, it will let me upload the file. But here I create the name or a new category. And next time, if I upload a document again, it will appear in my dropdown list here. And I can just select it here to upload a second file into the same category.
