+  We have only been playing with some of what git offers. In reality,
+  you can do much more with it. It also allows for a wide array of

+  \frametitle{Viewing}
+
+  In Linux, git uses the ``\bt{~/.gitconfig}'' file as its main
+  configuration file.
+  \bigskip
+  \pause
+
+  To see the current configuration values, use ``\bt{git config --list}''.
+  \begin{lstlisting}[language=none, caption=Git config values]
+    $ git config --list
+    user.name=bow
+    user.email=bow@bow.web.id

+  \frametitle{Modifying}
+
+  To edit the file directly, open ``\bt{~/.gitconfig}'' in a text editor
+  and save your changes.
+  \begin{lstlisting}[language=none, caption=Modifying the config file]
+    $ vim ~/.gitconfig
   \end{lstlisting}
   \bigskip
   \pause
+
+  You can also use the ``\bt{git config}'' to set the values via the shell.

+  \frametitle{Modifying: global ignore}
+
+  We will look at two examples now: setting a global ignore file and
+  setting aliases.
+  \bigskip
+  \pause
+
+  In addition to setting a directory-specific ``\bt{.gitignore}'' file,
+  you can also set a global ignore file.
+  \bigskip
+  \pause
+
+  You can name this file anything. The convention is to use
+  ``\bt{.gitignore\_global}'' and place the file in your home directory.

+
+  The global ignore file has the same format as the per-directory
+  ``\bt{.gitignore}'' file, only visible to all git repositories.

+  \pause

+  \begin{lstlisting}[language=none, caption=Setting the global ignore file]
+    $ echo "*.out" > ~/.gitignore_global
