Programming Ruby 3.2 (5th Edition): B2.0 page 323, $rdoc --help + easiest

@noelrappin

page 323, paragraph 4, line 2 : $rdoc ?

will likely use approximately never, see $rdoc --help for a full rundown.

The dollar prompt should be removed or separated by a blank, because the command is rdoc --help and is already in the special font for code literal.

+++++ in Using RDoc to Create Documentation for ri, paragraph 6, line 2 : easiest instead of easier ???

own use, it’s easiest to use the --ri option, which installs the documentation into ~/.rdoc:
       -----> ^^^^^^^

Can we say “it’s easiest”, not “it’s easier” ?

First Post!
