I added myself links to the Ruby on Rails Tutorial years ago, after
meeting Michael in a RailsConf.

By then, the book was a commercial product, but had a free online
version and I thought it could be a good resource complementing the
official documentation.

Nowadays, only a few sample chapters are available for free, and I
don't consider these links to be fair with the rest of commercial
books about Rails anymore.

A very minor change of comma usage.

Action Mailbox and Action Text belong to rails/rails since #34786 and #34873.

Just a small mention that we can use generators inside README.

My spellchecker flagged this as an incorrect spelling, upon further
research it appears to be a point of contention in English. Either way
might work.

After further examination queuing is much more common in the Rails
codebase so making this change will serve to standardize the spelling.

I think a prime concern people have here is sanitization and security.
Adding this word to the readme provides a little bit of clarity and
reassurance that we aren't just rendering raw data trusted from the
client.

after rails 5 its ApplicationController and ApplicationRecord

In order to make the recommendations consistent with Rails: https://github.com/rails/rails/commit/40b209db53

You cant run Action Text without Active Storage setup, so lets just set it up for you, rather than ask you to.

http links will be redirected to the https version, but still better to
just directly link to the https version.

Similarly to https://github.com/rails/rails/pull/32626/commits/9c3fe52f5fa9904b43bf76be13f85db57c223d0c

This is more like Action View than Active Model.

Just like we use has_many_attachments instead of active_storage_attachements.
