At the top is the name of the citation for the case: e.g. 403 U.S. 713, and the name of the case, e.g. NEW YORK TIMES CO. v. UNITED STATES and the court: e.g. SUPREME COURT OF THE UNITED STATES and the dates the case was argued and decided.
Next come the Headnotes. You probably won't need these.

Last are citations and footnotes. Again, you will probably not need them.
