Get started on Code Ignitor - Books, articles, sample projects?

[eluser]jackdowsan[/eluser]
Hello Guys!
I am new to CI, I have worked on OOP php and php in general. I know about MVC, but I haven't used it in my work yet. I am hoping all that to come from CI. But I want to have resources for that, book, blogs, articles..anything. A sample project that I can follow along and learn out of. A real world project may be.

Also, I want to know if there are any constraints in going with CI, anything that can't be done by using CI, I want to know before hand.

Thanks all, I appreciate you helping me out on this.

Regards
Jack
