CodeIgniter Setting URL

[eluser]LEECH[/eluser]
Hi! I'm new with codeigniter.I have created my website in my computer with this url:

Code:

http://localhost/mywebsite/index.php/home/home

How can I make its url like www.mywebsite.com , instead of www.mywebsite.com/index.php/home/home when I upload it to my web server?

Many thanks!
