Latest CI video tutorial?

So I'm a beginner in CI and intermediate in PHP. Everytime I watch or search a video tutorial in the net, it's always 2 or 4 years ago. I'm having a hard time following those (old) steps, because i think many features/best practices have changed(?). So I would like to request a CI tutorial with app creation like blog or please link me the easiest the latest video tutorial of CI. Thanks. And sorry I'm really noob and want to learn my first framework
