The first step in the appeal process is to file a Notice of Appeal. This notice is "jurisdictional", which means that the Court of Appeals cannot act if the Notice isn't filed. The notice must be filed within a certain period of time, usually 30 days for a civil appeal and 10 days for a criminal appeal, although in some matters in which the United States government is a party, the filing time may be longer. The time within which to file usually starts to run from the date of the entry of a Final Judgment in the District Court.
