Importing Yii Project Into Yii

Im new to yii and I need to insert yii project into the yii. I cant figure out the way to do it. It has a lot of folders for exampe- modules, config, controllers etc as well as some yiic file and yiic.bat and yiic.php At this point everything is set up(xampp server, yii framework).

I would really appreciate if somebody would help. Thanks.
