macos - How can I display the current branch and folder path in terminal?

Question

I've been watching some of the Team Treehouse videos and they have a very nice looking terminal when working with Git.

For example they have (something similar):

mike@treehouseMac: [/Work/test - feature-branch-name] $ git add .
mike@treehouseMac: [/Work/test - feature-branch-name] $ git commit -m "Some feature."
mike@treehouseMac: [/Work/test - feature-branch-name] $ git checkout master
mike@treehouseMac: [/Work/test - master] $ git status

How can my terminal show me some useful information of what branch I'm on, with colors to distinguish bits of the data I want? Is there some sort of de-facto plugin I haven't found yet?

I'm using Mac OSX 10.8

For anyone looking for how to do this in macOS Catalina or above (10.15+ incl. Big Sur 11.0) which has deprecated bash in favour of zsh, here is my .zshrc file:

parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^* (.*)/[1]/p'
}
COLOR_DEF='%f'
COLOR_USR='%F{243}'
COLOR_DIR='%F{197}'
COLOR_GIT='%F{39}'
NEWLINE=$'
'
setopt PROMPT_SUBST
export PROMPT='${COLOR_USR}%n@%M ${COLOR_DIR}%d ${COLOR_GIT}$(parse_git_branch)${COLOR_DEF}${NEWLINE}%% '

If you don't like the colours I have used, replace the 243/197/39 values with the colour codes as defined here: https://misc.flogisoft.com/bash/tip_colors_and_formatting
