I have played around with Ruby on Rails before but this course really helped me understand the nots and bolts. It is worth replicating all the examples shown in the videos to get a good understanding,

By MBMay 2nd 2016

Good intro, nice to mix in the various concepts that I will be working with as well (Heroku, Git, etc.). Also appreciated the Java comparisons since I have been working in Java for 15 years.
