The pull serves to update the existing data on your machine, to clone the repository you must use the clone:
$ git clone <url>.git repo
$ cd repo
When making changes you must first make the commit and then give the push:
$ git add <file> <file>
$ git commit -m 'descrição do commit'
$ git push origin master -u
When the repository is cloned origin is comes configured.
To update the repository on another PC, use pull (the repository must be previously cloned).
$ git pull origin master
Or in some cases
$ git pull
Sometimes it may not work with the origin master, This also holds true for the push (Own experience).
If more than one person uses the repository, always a
pullbefore giving thepush.

OK thanks, the more the problem was another had to add credentials to the TFS repository in order to download the project thank you.
