No idea what's going on in this video

Besides the conceptual overview, I know we are adding gems (or libraries, am I right?) to this specific application, I have no idea what's going on. I understand the git stuff and the prerequisites but other than that.. Have no idea what he was walking me through on a low-level.

Can you post a link to the lesson? Maybe I can help.

It might be better ask specifically about what you don't understand so we try to explain. Do you have any question?

I am also lost. We are walked through different steps without any explanation of what the purpose of those steps is.

The rspec-rails and Capybara are both gems (or third party libraries of functionality) that aid in testing. If you have done any jQuery courses, think of them a bit like a jQuery plugin. In other words, these are small bits of code that other developers have worked on that you can incorporate into your program. The group :development, :test do etc stuff are Ruby (code) blocks that allow you to set rspec-rails and Capybara to your development/test and test groups respectively. If you don't know what a Ruby block is, I recommend taking some of the courses in the Learn Ruby track.

I agree. There is no specific question at this point as it all seems totally obscure. What is a capybara thing? What is a rspec-rails for? not to mention what all those folders and their contents are for. If one follows the track "rails" there is a huge gap between the very clear and slow introduction into Ruby and JavaScript and this part of the track, which all of a sudden seems to jump to an intermediate or advanced level.

I understand. I'm in the same boat. I'm hoping everything becomes clear later on because right now I'm just blindly following along and doing as he says but I have no idea why we are doing each step or what the outcome will be.
