I am wanting to install CodeIgnitor on my hosting account, but I'm a little confused.

The documentation says:

I'm having trouble getting my head around No. 2; It says to chuck everything into the root dir of my server, which is fine, I can do that, BUT, the codeigniter files that I upload also has an index.php page.

And my website files are also located in the root folder. If I upload all the codeigniter files to my root dir, and replace the default index.php file that codeigniter tells me to upload with my own websites index.php file? Is that what you're supposed to do?

Thanks :)
