Script delete itself

Hi guys

I´m pretty new with powershell and i´m a little bit blind in some things.

I´ve created a script to set up several features and install several pieces of software just running this script. 

For that I´ve allocated a folder in c: drive in my windows 2012 template. 

What I´d like to know if is there any way to delete that folder, script include, once everything is done? I mean, something like add a line at the end of the script and just saying, your last step is delete the whole folder.

Thanks, any help would be really appreciated.
