Removing index.php from my joomla website url?

I am using Joomla in my website, and if found all the articles that i create in Joomla has link structure like

"http://www.mysite.com/index.php/about-us"...

How do i remove the index.php from the link? so that my link would look like

"http://www.mysite.com/about-us"

FYI : I have configured joomla with IIS.It seems .htaccess file have some role to play in this,but it seems to be not working in IIS. Any suggestions开发者_StackOverflow社区?

This configuration should work:

http://docs.joomla.org/SEO_and_IIS#web.config

You can configure that in the adminpanel of joomla. Go to the general settings and activate mod_rewrite

Look here:

I don't really know how to use it, but hope this helps.

Just rename the htaccess file by putting the (.) before the file name and remove the extension and all is done.
