 ## Usage
 
-Rubocop 0.68 removed performance cops and 0.72 removed Rails cops. However, upgrading `rubocop-github` without modification will almost definitely create very many new offenses. The current version of this gem exposes the "legacy" configuration under `config/default.yml` and `config/rails.yml` which should be used *if and only if* the version of rubocop is locked to `< 0.68` in your project (which it should be unless you `bundle update rubocop`). It also exposes an "edge" configuration under `config/default_edge.yml` and `config/rails_edge.yml` so that the changes can be tested without introducing breaking changes.
