GIT repository problem

We have a 3rd party developer try to give us the updates thru their repository...

Problem is the instruction isn't clear on how to do the update.  They expect everyone to know this.

The development manager just placed the command (git pull origin master).  I tried running the command in gitbash.  Without any instruction of specific folder to be in.  Did he expect me to know this, when I have no idea how GIT worked in the first place.  Thanks to the internet, now I know why I get the error:

Fatal: Not a git repository (or any parent directories): .git

He should have instructed me to change my directory to the one I cloned before.  Thanks to the internet I found the solution here: http://stackoverflow.com/questions/11961600/fatal-not-a-git-repository-or-any-of-the-parent-directories-from-git-status

You have to actually cd into the directory first:

$ git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts
