+macOS uses Homebrew's [`command-not-found` clone][2]. This module will
+automatically load it without needing to manually source `handler.sh` from
+`.zshrc` per the [instructions][3].

+Note: Prior to [Homebrew 4.6.12][4], you may have also needed to tap the
+[`command-not-found` Homebrew repository][5]. This will still work as a
+fallback when the `command-not-found` handler can't be detected in Homebrew
+core, but the repository has been deprecated and may print a warning. After
+upgrading Homebrew, it can be untapped.
