To add a link to a PDF or Word doc, add the text title for your link on the page & then highlight it and click on the hyperlink button on the toolbar.
Then click on the little icon to the right of the address field that looks like
a folder, this will bring up the assets manager. Down the left side of the
asset manager, you will find an upload function, select browse to locate the
file and then upload. (if the file is very large you may need to send it to support@dogwebs.com to get it uploaded)

Once uploaded you will see the file on the right side, select it and click OK.
You will see the address has been added, so select insert.
