Hi @AlJohri

I guess you were trying to deploy to heroku, right?

In current version of README, right before the code snippet that you copied here it says Run bundle

"bundle" without any arguments is equivalent to "bundle install"

so, README looks fine to me in this regard.

@nfedyashev Ah, sorry I completely missed that!
