How to add information to about screen of my cocoa app in Mac Os X

I am pretty new in developing cocoa applications. I have developed a small UI application using cocoa. I wanted to add some information on about screen, currently it shows the app name and version which is 1.00. Can any one help me how i can add some information in about screen, is it possible to add infor开发者_运维技巧mation programmatically instead of hard coding it ?

Any help will be appreciated.

Create a file Credits.rtf or Credits.html in the application bundle, containing the extra information. If that file exists, AppKit displays it in the standard about panel.
