# 2) Added the following line to your .bashrc:
# source ~/.git-completion.sh
#
+# Or, add the following lines to your .zshrc:
+# autoload bashcompinit
+# bashcompinit
+# source ~/.git-completion.sh
+#
# 3) Consider changing your PS1 to also show the current branch:
# PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
#
# set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
# untracked files, then a '%' will be shown next to the branch name.
#
+# If you would like to see the difference between HEAD and its
+# upstream, set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates
+# you are behind, ">" indicates you are ahead, and "<>"
+# indicates you have diverged. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated
+# list of values:
+# verbose show number of commits ahead/behind (+/-) upstream
+# legacy don't use the '--count' option available in recent
+# versions of git-rev-list
+# git always compare HEAD to @{upstream}
+# svn always compare HEAD to your SVN upstream
+# By default, __git_ps1 will compare HEAD to your SVN upstream
+# if it can find one, or @{upstream} otherwise. Once you have
+# set GIT_PS1_SHOWUPSTREAM, you can override it on a
+# per-repository basis by setting the bash.showUpstream config
+# variable.
