According to pr #22443 in the guides there's always a dollar sign before every command, so why is in the main README a `$` and in every submodule a `%`?
Just eye candy..
I think we are better off leaving `sudo` outside of the documented
way of installing gems (`activerecord`, `actionpack`, …).
We don’t want newbies to think that `sudo` is required or, even worse, than
they actually have to type `[sudo] gem install`.
In most scenarios, `sudo` is not needed to install gems, and people who do
need it, probably already know about it.
What do you think? 😁
