2.git remote Add upstream Git@github.com:xyz/abc.git connect to the library you fork (upstream, local)

3.git Checkout-b Dev Create a new local branch that can be called dev, or you can name it whatever you want.

4.git fetch upstream Remote Fork library take code fetch down to local (upstream code-local)
