I am learning guitar seriously through the course and have been learning through the acoustic journey, enjoying myself. But once I am done, my dream is to really learn how to play jazz. 

What is the best way to start learning jazz? I do not really see an official step by step course like the other 4 topics (rock, country, blues, and acoustic) and there are many tutorials from different teachers when I search through the jazz topic in this website. 

Should I learn blues too to help learn jazz quicker? Where did many jazz players start after having enough experience with guitar?

Thanks
