Some live events work best when accompanied by extras - this can be anything (pdf, jpg, word document, etc.) that a customer will be to download and use along with the live event. After Uploading Extras, you can add them to live events so that the extra will appear under Resources on the video page.
Navigate to the live event you want to add extras for under Content > Live Events and click Edit. Under the Extras tab click Choose File to add an extra.
