-# Copyright (C) 2006 Shawn Pearce
+# Copyright (C) 2006,2007 Shawn Pearce
 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
 #
 # The contained completion routines provide support for completing:
 #    2) Added the following line to your .bashrc:
 #        source ~/.git-completion.sh
 #
+#    3) You may want to make sure the git executable is available
+#       in your PATH before this script is sourced, as some caching
+#       is performed while the script loads.  If git isn't found
+#       at source time then all lookups will be done on demand,
+#       which may be slightly slower.
+#
+#    4) Consider changing your PS1 to also show the current branch:
+#        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+#
+#       The argument to __git_ps1 will be displayed only if you
+#       are currently in a git repository.  The %s token will be
+#       the name of the current branch.
