How to Learn Cinder? (tutorials)

I had pause from programing and I am back. Before I only watched examples, and now I want do something own and learn how to use Cinder. There are some tutorials, but there is written, it is outdated. It is worth to look at it for how to use cinder? Or is there another way how to learn it?

Cinder comes with an excellent collection of sample projects. I would recommend them as a starting point.

Perhaps this is a good starting point:
https://libcinder.org/docs/guides/opengl/index.html

Examples which are provided with different cinder version are good to start. But as far as the concern is Graphical development going through openGl stuff will be good approach prior to Cinder.

Thanks all for answers.
