Opening new proyect

HI, I start a new job where they work with cakephp 2.x. I install all in my pc, and throught github I clone 2 repositories of two diferent proyects already functionin perfectly.
Now I need to creat a new proyect. Not related with the others. And I don’t know how to do it. I am working with xampp where the proyect are saved in htdocs file, and with phpstorm as IDE.
I can open a proyect but I don’t know how to do to see inside my proyect de cakephp structure (app/ lib/ plugins/ vendors/ htaccess index.php README).

Have you read this : Installation - 2.x ?
You can retrieve a empty project from github.
