hey emad,
do you mean you want the homepage of your site to be easysocial?

if so create a menu item in your joomla menu and select one of the easysocial menu links - for example the dashboard or login layout.
then set this menu item to "default" by clicking on the star icon in the "home" column. it should look like this at the end: http://screencast.com/t/93i2JPBR1
