By going to Media in the main menu you will be able to add files and media to your website. This can be handy if you want to upload a PDF and create a link for the file that you can share with others via your website or perhaps via email. Once you are on the media page you can simply drag and drop a file from your computer anywhere on the screen and it will begin uploading the file, or alternatively you can click the Add New button at the top. Once your file is uploaded you will see a URL field. Simply copy this URL address and paste it wherever you want. 

From the media page you can also select, preview, edit and delete media items by clicking on them.
