 In this tutorial, we have learnt to,
 
 \begin{itemize}
 \item Undo changes to the repository using hg revert,
 \item View changes done to the repository using hg diff
 \item Use revision numbers as arguments to different hg commands
-\item Clone repositories, using hg clone,
-\item Serve our repositories via http using hg serve,
-\item push changes to a repository using hg push,
-\item check the changesets in a repository after last pull, using hg incoming,
-\item pull changes from a repository using hg pull ,
-\item update the working directory, using hg update,
-\item merge two heads, using hg merge,
-\item and resolve conflicts using hg resolve.
