How are all courts, except the us supreme court, established?

The United States is considered to have a dual court system, since it has both a federal judiciary and state judiciaries. State courts are established by each state, and these vary from state to state. Each of these courts, federal and state, have specific jurisdictions and operate at the same time, and sometimes, the federal and state courts have shared jurisdiction (concurrent).
