This ancillary section should be used only to provide secondary information that is relevant to the research project. For example, if you are collaborating with another investigator, it is appropriate to obtain a letter from him/her indicating his/her willingness to collaborate and detailing what specific support (personnel, equipment, research materials, results, etc.) they are willing to provide for the research project. Some funding programs do not allow investigators to submit appendices so be sure to find out in advance whether or not you can submit supporting materials and what if any limitations there may be concerning these materials (content, page limits, etc.).
