include the following:

1. A physical or electronic signature of the copyright holder or a person authorized to act on his or her behalf;
   
   
2. A description of the copyrighted work claimed to have been infringed and multiple copyrighted works at a single
   online site are covered by a single notification, a representative list of such works at that site;
   
   
3. A description of the material that is claimed to be infringing or to be the subject of infringing activity, and
   information reasonably sufficient to permit the service provider to locate the material;
   
   
4. Information reasonably sufficient to permit the service provider to contact you, such as an address, telephone
   number, and, if available, an electronic mail address;
   
   
5. A statement that you have a good faith belief that use of the material in the manner complained of is not authorized
   by the copyright owner, its agent, or the law; and
   
   
6. A statement that the information in the notification is accurate, and under penalty of perjury, that you are authorized
