Clone to your computer

• note The $ below means "Type this in the Terminal". When writing the following Terminal commands, ignore the $ and type the rest. You will see people represent the Terminal on sites like Stackoverflow with the $. Repeat. You don't need to type the $. (Don't confuse this $ with the $ from jQuery)

$ git clone [email protected]:kingluddite/catchup-03-node-express.git

Pull down all branches

• Each of the lessons will be contained inside their own branches. You need to pull down these remote branches to your local machine

• Use the following two commands to pull remote branches down to your local machine

• $ git fetch --all

• $ git pull --all

• $ git branch -a (will show you remote branches)

Checkout branches locally

• To focus more on the code we will just checkout a branch to work on the next lesson
• You have access to the repo after the Catchup so you can play around with the code (the best way to learn how to code is.... to code)
• To checkout a branch just type any of the following to checkout that particular branch
• To see all your branches you can type $ git branch, (you won't see a list of the branches until you check each one out individually)
• To break out of the list of branches type q for quit

Clear a branch of work you don't want to commit

$ git checkout -- .

$ git checkout master
$ git checkout 01-console-log
$ git checkout 02-argv
