@noelrappin page 355, paragraph 3, line 2 : ```auto figuration or by running rubocop -a to auto correct (which will fix all but the first issue). -----> ^^^ ``` This seems correct looking at the report : ```auto % rubocop Inspecting 13 files ..C...C...... ... 13 files inspected, 4 offenses detected, 3 offenses auto-correctable ``` but is not fully true. In fact `rubocop -a` finds three new offenses in `spec.metadata`, corrects them but **corrects only two of the three** offenses declared previously as auto-correctable (`aaagmnr.gemspec:5:1`, `14:32`, but not `options.rb:11:26`), saying "_1 more offense can be corrected with `rubocop -A`_ " : ```auto % rubocop -a Inspecting 13 files ..C...C...... Offenses: aaagmnr.gemspec:5:1: C: [Corrected] Gemspec/RequireMFA: metadata['rubygems_mfa_required'] must be set to 'true'.

Okay that’s true, and I’ve cleaned up the text to better reflect the reality.
