You can also download a manual from many company websites like Ruger or Springfield Armory. Downloads are free too.

Be sure to have this either on the cover or near the front of your manual. 1) Treat every weapon as if it were loaded 2) Never point a weapon at anything you do not intend to shoot. 3) Keep trigger finger straight and off the trigger until you are ready to fire 4) Keep weapon on safe until you intend to fire. As noted in another answer, many firearms manufacturers will readily provide manuals for their weapons free of charge. Don't forget to check your local library or request an inter-library loan if need be. If your question is not so much what to put in your manual but how do you use your word processor or desktop publishing program to create a table of contents and cover page, then most programs offer a Help option at the far right of their menu bar. A Google search can also yield manuals and tutorials for your specific programs.
