how to make initial configurations in git

I have joined a private reposito开发者_如何学Pythonry for project sharing using git. What are the initial configuration I have to make locally( like username, pwd) to connect to the repository? How am i supposed to connect my local git with the repository? The repository provided me with the following git link git@<domain>:<username>/<project>.git

to download the repository locally just do:

git clone git@<domain>:<username>/<project>.git

I'd also recommend spending some time at the following git site to learn the basics: http://gitimmersion.com/
