Referral Sources can be managed in your company settings by navigating to settings-> Sales -> Referral Sources

**Note**
​Do not add any lead providers to your referral source list.  These will be automatically added when you enable a lead provider.  Adding these manually will cause those items to be duplicated.

Several actions can be performed on the referral sources list.

Add Row: Clicking add row will show a slide-out that will allow you to add an item to the list.

Edit: Clicking the three dots menu at the end of a row will allow you to edit the name of an existing item

Delete: Clicking the three dots menu at the end of a row will also allow you to delete the entry entirely.
