 If you ever need help while using Git, there are three ways to get the manual page (manpage) help for any of the Git commands:
 
-  $ git help <verb>
-  $ git <verb> --help
-  $ man git-<verb>
+[source,console]
+----
+$ git help <verb>
+$ git <verb> --help
+$ man git-<verb>
+----
 
 For example, you can get the manpage help for the config command by running(((git commands, help)))
 
-  $ git help config
+[source,console]
+----
+$ git help config
+----
 
 These commands are nice because you can access them anywhere, even offline.
 If the manpages and this book aren't enough and you need in-person help, you can try the `#git` or `#github` channel on the Freenode IRC server (irc.freenode.net).
