Lists in LaTeX

\begin{itemize}
  \item LaTeX handles all formatting automatically.
  \item You just add \item for each entry.
  \item Nested lists indent automatically:
  \begin{itemize}
    \item Second level uses a dash by default.
    \begin{itemize}
      \item Third level uses an asterisk.
    \end{itemize}
  \end{itemize}
\end{itemize}

\begin{enumerate}
  \item First item (1.)
  \item Second item (2.)
  \begin{enumerate}
    \item Nested (a.) — uses letters by default
    \item Second nested item
  \end{enumerate}
  \item Back to top level (3.)
\end{enumerate}
