Learning how configure correctly

[eluser]Unknown[/eluser]
I am using xampp and my document root in apache is set to htdocs directory by default. I download Codeigniter and unzip the project into this directory. It runs fine. Now I would like to use CI to create my own project. In the controllers folder I would like to create a folder named "myproject" and in the views folder of application folder, I would like to create a folder named "myproject_view" in which I will store all of my view files. My problem is I don't know how to reset my config file (especially the route.php) for my project to work then.

CodeIgniter documentation doesn't have a section to specify how to do this, the information given in URI Routing chapter is not enough for readers to understand this at all. Plus, What if I also would like to store my controler files in a nested folder (controllers > somefolder > someanotherfolders > etc) ? Thank you very much.
