How to start a project with CodeIgniter?

[eluser]Mauricio de Abreu Antunes[/eluser]
Thanks for all!
I noticed that my .htaccess was not overwriting my httpd.conf.
Sorry guys!

But its ok now:

RewriteEngine on
RewriteBase /
RewriteCond $1 !^(index\.php|css|js|images|robots.txt)
RewriteRule ^(.*)$ /percutz/index.php?/$1 [L]

It's my .htacces. Any suggestions?
Ok, i have another issue now: when i go for http://localhost/percutz/index (like index.php), why am i getting Page Not Found?
I need to go http://localhost/percutz for access to my new "home" and not localhost/percutz/index?
Can i redirect http://localhost/percutz/index to http://localhost/ with no php redirect?

Btw, thanks again! I'm learning PHP. I program Oracle and ASP.Net.
