 Here we get the date of the commit (in YYYY-MM-DD format), followed by an abbreviated commit hash, the name of the comitter (important if you have more than one person working on this project), and finally the commit description.
 
+\section{Examinging Earlier Commits}
+
+Now that you know how to find earlier commits, you need to know how to revert to one. To do that, you simply \texttt{checkout} the earlier commit, using just enough of the SHA-1 hash to be identifiable:
+
+\input{include/gitcheckoutcommit}
+
+In this case, this would take me back to the ``Significant additions to branching chapter'' commit.
+
+To get back to the latest commit, we simply checkout our current branch, which in this case is ``main'':
+
+\input{include/gitcheckoutmain}
+
+Of course, the easiest way to view older commits and examine them is by using a \textit{remote} repository, because their graphical interface is far easier to navigate.
