Hi @nasirahamed,
You can find a thorough documentation of T3 Framework in here, that includes its layout and configuration
By reading those resource, you shall understand that T3 framework working based on blocks. You can add or remove blocks as you wish.
I suggest you to edit the home.php, but before you proceed, let’s make a copy of it, just for precaution. Once you’ve done making a copy, you can proceed so it resembles like
<?php $this->loadBlock('top-header') ?>
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock ('slideshow') ?>
<?php $this->loadBlock('mainbody') ?>
<?php $this->loadBlock ('masshead') ?>
<?php $this->loadBlock('footer') ?>
once you saved it, you can then assign this layout to your needs
Hope this helps
