For projects that are expected to grow, it is a good idea add comments your
Gemfile. That way, even in large setups you will still know what each gem does even if the name is not self-explanatory and you added it 2 years ago.
This can also help you to remember why you chose a certain version and consequently re-evaluate the version requirement later on.
