Gems newbie - patience appreciated...

[Iron Phoenix]

As indicated, I'm new to gems. I have only the vaguest idea about them as addons. How new?  I don't even know what "rails" is yet... "rake" has something to do with C, right?

Reasonably familiar with Ruby without using gems/rails/rake.

Anyway...

Windows 11

Ruby 3.3.7 (w devkit)

Gems 3.5.22

I need to access XML files now.  The "standard" for this seems to be nokogiri.

I installed nokogiri, using this command in irb:

system "gem install nokogiri"

My stupid question is - how do I do the "require"...?  It does not accept just 

require 'nokogiri'

Thank you in advance...
