There's two helpful commands which allow you to create lists very easily.
\enumerate creates a numbered list and \itemize a list with
dots instead of numbers. These commands are an example for a
\begin{ command } \end{
command }
environment. The listed items have to begin with \item.
\begin{enumerate}
\item Troubadix {\bf is} a marvellous musician!
\item Obelix is {\bf not} fat!
\end{enumerate}
\begin{itemize}
\item Verleihnix
\item Raffnix
\item Idefix
\end{itemize}
