-# This script allows you to see the current branch in your prompt.
+# This script allows you to see repository status in your prompt.
#
# To enable:
#
# 3a) Change your PS1 to call __git_ps1 as
# command-substitution:
# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-# ZSH: PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
# the optional argument will be used as format string.
-# 3b) Alternatively, for a slighly faster prompt, if you are
-# using bash, __git_ps1 can be used for PROMPT_COMMAND
+# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
# with two parameters, <pre> and <post>, which are strings
# you would put in $PS1 before and after the status string
# generated by the git-prompt machinery. e.g.
# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+# will show username, at-sign, host, colon, cwd, then
+# various status string, followed by dollar and SP, as
+# your prompt.
# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
-# will show username, at-sign, host, colon, cwd, then
-# various status string, followed by dollar and SP, as
-# your prompt.
+# will show username, pipe, then various status string,
+# followed by colon, cwd, dollar and SP, as your prompt.
# Optionally, you can supply a third argument with a printf
# format string to finetune the output of the branch status
#
-# 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.
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
#
# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
# unstaged (*) and staged (+) changes will be shown next to the branch
#
# If you would like a colored hint about the current dirty state, set
# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
-# the colored output of "git status -sb".
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd.
