You can upload a wide range of documents to your account. While documents are uploaded in the editor, like images, they are attached to your account and can be used with any of your websites.
To upload a document or file:
1. Click the Documents icon on the Add tab of the main toolbar to access the Document Management window.
2. Select a collection to which you want to add a document. You can also create a new collection by clicking on Add Collection, or select All Documents to not add the documents to a collection (you can always do this later).
3. Click the Upload Documents button at the top right of the window.
4. Select the desired documents. Once uploaded they will appear in the selected folder.
