Fixed example

The cd /ANY/PATH should still be there because git clone will create a new directory with the same name as the repository in the current directory. The instruction is meant to be idiot-proof. Your addition of the cd minica is correct since go build needs to be run in the source/repo directory.

@jpickwell should it be merged ? Or I close it, too old
