In other words, you can't sue me if it breaks.  ;)

Add spell names and IDs to whitelist to the first line, inside the {} brackets. To add a new spell ID, add the following INSIDE the closing `}`:

  [0]=1,

where 0 is replaced by the spell ID. Do not forget the comma afterward.

To add a new spell NAME, add the following INSIDE the closing `}`:

  ["NAME"]=1,

where NAME is replaced by the exact spell name (case-sensitive!). Do not forget the quotation marks (") or the comma afterward.
