\begin{document}
\noindent An example of a new list is \texttt{steps}:
\begin{steps}[label=\arabic*:]
\item Lists are declared with \verb=\newlist=.
\item But this is not enough:
  \begin{steps}[label=\alph*)]
  \item as a minimum we need to define a \texttt{label}.
  \item this is done here locally on each environment.
  \end{steps}
\item Usually, \verb=\setlist= is used for this.
\end{steps}
