  ### Pry for Rails console

  [Pry](https://rubygems.org/gems/pry) is a runtime developer console and IRB
  alternative with powerful introspection capabilities. Pry aims to be more than
  an IRB replacement. It is an attempt to bring [REPL driven programming](https://pry.github.io/)
  to the Ruby language.

  [byebug](https://rubygems.org/gems/pry-byebug) adds 'step', 'next', 'finish', 'continue'
  and 'break' commands to control execution.

  Add to your `~/.pryrc`:

  ```ruby
  Pry.config.prompt = PryRails::RAILS_PROMPT if defined?(PryRails::RAILS_PROMPT)
  ```
  EOF
end

do_commit

print_green "\nAdded Pry successfully!"
