It's basically zero setup. If you don't have a Git repo for your 
project, the setup is 'git init'. The repo is the project, and the 
project files are all the non-ignored files in its root directory 
(registered or not). At least, that's with the built-in 'vc' backend.

To get the most benefit from the package, you should install the latest 
version from GNU ELPA ('M-x list-packages', then install 'project'). The 
latest version is 0.5.2.

To see the full list of commands defined in that package, type 'C-x p C-h'.

You can also read the full description of the package with 'C-h P 
project RET'.
