# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
# 2) Add the following line to your .bashrc/.zshrc:
# source ~/.git-completion.sh
-#
-# 3) Consider changing your PS1 to also show the current branch:
-# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-# ZSH: PS1='[%n@%m %c$(__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.
-#
-# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
-# value, unstaged (*) and staged (+) changes will be shown next
-# to the branch name. You can configure this per-repository
-# with the bash.showDirtyState variable, which defaults to true
-# once GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-# You can also see if currently something is stashed, by setting
-# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-# then a '$' will be shown next to the branch name.
-#
-# If you would like to see if there're untracked files, then you can
-# 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.
-#
+# 3) Consider changing your PS1 to also show the current branch,
+# see git-prompt.sh for details.
