bouendeu I don't have that, but I have the following:
Beginning Ruby - From Novice to Professional (3rd Edition) (EPUB)
Ruby For Kids For Dummies (By Christopher Haupt) (PDF)
Ruby on Rails Tutorial - Learn Web Development with Rails, 4th Edition (By Michael Hartl) (PDF)
Let me know if these would help. (P.S. I am working on increasing my trust level.)
