claudiob 0080a886b2 [ci skip] Don’t encourage sudo gem install
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? 😁

= Action Pack -- From request to response
Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.
It consists of several modules:
* Action Dispatch, which parses information about the web request, handles
routing as defined by the user, and does advanced processing related to HTTP
such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
handling HTTP caching logic, cookies and sessions.
* Action Controller, which provides a base controller class that can be
subclassed to implement filters and actions to handle requests. The result
of an action is typically content generated from views.
With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
