Some Live Events work best when accompanied by extras—this can be anything (pdf, jpg, word document, audio, etc.) that a customer can download and use along with the event. After Uploading Extras, you can add them to your Live Event so they will appear under Resources on the event's page.
Navigate to Content, go to Live Events, then on the live event you want to add extras to, click Edit. Under the Extras tab, click Choose File to add extras. Select the Extra(s) you want to add and then Save.
