Hi , I have two urls. I have written them below

1.<a href=”index.php?software=ture”>Software</a>
2.<a href=”index.php?contact=ture”>Contact</a>

What i want to do is that I need to remove the file name and .extention from both of the urls. I am using wamp server on windows xp.
My url should be like this in the addressbar,
1.Mydomain/?software=ture.
2.Mydomain/?contact=ture .

I have heared about htaccess. But I don’t know how to do that.
I have witten my full code below.
