You can upload a wide range of documents to your account. While documents are uploaded in the editor, like images, they attached to your account and can be used with any of your websites.
To upload a document or file:
1. Click the Add tab on the left toolbar and then select the Documents option to access the document manager.
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)
