Actually this is exactly how I started learning openGL. Be it a new language or new framework always follow these steps. Read it. Maybe couple of times (say only chapters 1-3) in the beginning. Understand the basic mechanism first rather than try out a program copied from somewhere else. Start testing out simple things. I'm lucky to not have fallen for all the blog posts/tutorials on openGL where they spit out a C file and say to compile and run it.
